  6. Variable Variables are nothing but reserved memory locations to store values. This means that when you create a variable you reserve some space in memory. Memory ` X = 25 int X = 25; float Y = 3.142857; boolean B = true; Y = 3.142857 B = true EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  7. Data types Conditional Statements Classes and Objects Arrays & Strings ` Functions Operators Loops Variables EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  8. Data types A data type, in programming, is a classification that specifies which type of value a variable has and what type of mathematical, relational or logical operations can be applied to it without causing an error. Memory ` Integer X = 25 int X = 25; float Y = 3.142857; boolean B = true; Float Y = 3.142857 Boolean B = true EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  9. Data types Data types Float Boolean ` Integer Character EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  10. Numeric Data type  Integer data types are used to store numeric values.  There are four different integer types in Java: Integer 1 Float 3 2 byte Type -128 to 127 ` short Type -32768 to 32167 Character 3 -2147483648 to 2147483647 int Type Boolean 4 -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807 long Type EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  11. Float Data type  Float data types are used to store numeric values along with their decimal value.  There are two different float types in Java: Integer 1 32 Float ` float Type ±3.40282347E+38F Character 3 Boolean 4 double Type ±1.79769313486231570E+308 EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  12. Character Data type  Character data types are used to store character values.  char data type is a single 16-bit Unicode character: Integer 1 Float 3 2 ` Character 3 char Type 0 to 65,535 Boolean 4 EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  13. Boolean Data type  Boolean data types are used to store boolean values along.  This data type is used for simple flags that track true/false conditions Integer 1 Float 3 2 ` Character 3 boolean Type True or false Boolean 4 EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  14. Conditional Statements Classes and Objects Arrays & Strings Data types ` Functions Loops Variables Operators EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  15. Data Operations Operations Operators are the constructs which can manipulate the value of operands. Arithmetic Operators Relational Operators ` Operators Unary Operators Logical Operators EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  16. Arithmetic and Relational Operators Relational Arithmetic a + b Addition a == b Equal To ` a != b a – b Not Equal To Subtraction a > b Greater Than a * b Multiplication a < b Less Than a / b Division a >= b Greater Than Equal To a % b Modulus a <= b Less Than Equal To EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  17. Unary Operator There are two types of unary operators: Increment and Decrement Pre increment ++i Increment ` Post increment i++ Pre decrement --i Decrement i-- Post decrement EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  18. Logical Operator There are three types of logical operators: Logical AND, Logical NOT, Logical OR Returns a if a is false, b otherwise a and b ` Returns b if b is false, a otherwise a or b Returns true if a is false, false otherwise not a EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  19. Conditional Statements Classes and Objects Arrays & Strings ` Data types Functions Loops Operators Variables EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  20. Conditional Statements If Statement Start Syntax: If Condition ` TRUE FALSE If code End EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  21. Conditional Statements Else If Statement Start Syntax: FALSE If Else If Condition Condition ` FALSE TRUE TRUE If code Else If code End EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  22. Conditional Statements Else Statement Start Syntax: FALSE If Else If Condition Condition ` FALSE TRUE TRUE Else code If code Else If code End EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  23. Conditional Statements Start Switch case Statement switch Condition Syntax: Case value1 Statement 1 break ` Case value2 Statement 2 break Case value3 Statement 3 break default Statement End EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  24. Conditional Statements Classes and Objects Arrays & Strings Data types ` Functions Operators Variables Loops EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  25. Loops in Java A loop statement allows us to execute a statement or group of statements multiple times. The following diagram illustrates a loop statement: Loops START Loops ` FALSE CHECK CONDITION TRUE repeat while EXIT LOOP do while for EXECUTE BLOCK EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  26. Do While Loop Repeats a statement or group of statements while a given condition is TRUE. It tests the condition after executing the loop body. Do While Loop Syntax: START ` EXECUTE BLOCK repeat FALSE CHECK CONDITION TRUE EXIT LOOP EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  27. While Loop Repeats a statement or group of statements while a given condition is TRUE. It tests the condition before executing the loop body. While Loop Syntax: START ` FALSE CHECK CONDITION TRUE repeat EXIT LOOP EXECUTE BLOCK EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  28. For Loop Repeats a statement or group of for a fixed number of times. It tests the condition before executing the loop body. For Loop Syntax: START Initialization ` FALSE Check condition Exit loop TRUE repeat Execute Statements Iteration EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  29. Arrays & Strings Conditional Statements Classes and Objects Data types ` Functions Operators Variables Loops EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  30. Array In Java  An array is a data structure which holds the sequential elements of the same type.  Arrays of any type can be created and may have one or more dimensions. 0 1 2 3 4 ` E.g: array index 4 is holding a value of 200 Index 126 32 230 21 200 Value Each index in the array holds a value. EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  31. Array In Java  Arrays can be of 2 types: Multi Dimensional Array Single Dimensional Array Initialization: int table[][] = new int[4][5]; Table[2][2] = 13 Initialization: int a[] = new int[12] ` Index in Y dimension 0 1 2 3 4 0 1 2 3 Index in X dimension Height =4 Width = 5 EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  32. String In Java  String is a data structure which holds the sequential character.  In Java programming language, strings are treated as objects. 0 1 2 3 4 5 ` Initialization: String str = “Hello” H e l l o \0 Str[2] Str[3] Str[4] Str[5] Str[0] Str[1] EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  34. Functions In Java A function is a block of organized, reusable code that is used to perform a single, related action. Functions Function Add Functions ` Return 8 Call 1 Call (3,5) Return 15 Call 2 Predefined Functions User Defined Functions Call (6,9) Call 3 Return 6 Call (1,5) EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training

  36. Classes and Objects in Python  A class is the blueprint from which specific objects are created.  Anything that has a state and behavior is object. Classes and Objects ` Class Object EDUREKA JAVA CERTIFICATION TRAINING https://www.edureka.co/java-j2ee-soa-training
