Operators in java By cheena
- 2. Java is a popular programming language, created in 1995. Applications of JAVA: * Mobile applications (specially Android apps) * Desktop applications * Web applications * Web servers and application servers * Games * Database connection * And much, much more!
- 3. Operator An operator is a symbol that operates on one or more arguments to produce a result. Java provides a rich set of operators to manipulate variables.
- 4. OPERANDS
- 7. Increment Operator is Used to Increment Value Stored inside Variable on which it is operating. Decrement Operator is used to decrement value of Variable by 1
- 8. a = a + 1; a + + ; or + + a ; a = a - 1; a - - ; or - - a ; Common Shorthand
- 10. The arithmetic operators are used to construct mathematical expressions as in algebra. Their operands are of numeric type.
- 13. A shift operator performs bit manipulation on data by shifting the bits of its first operand right or left.
- 14. Left Shift Right Shift << >> >>>
- 16. Example of Left Shift
- 17. A relational operator compares two values and determines the relationship between them. For example: ! = returns true if its two operands are unequal. Relational operators are used to test whether two values are equal, whether one value is greater than another.
- 18. Relational Operators > < >= <= == != Primitives • Greater Than : > • Less Than : < • Greater Than or Equal : >= • Less Than or Equal : <= Primitives or Object References • Equal (Equivalent) :== • Not Equal : != The Result is Always true or false
- 20. The bitwise operators are similar to the logical operators, except that they work on a smaller scale -- binary representations of data.
- 22. These logical operators work only on boolean operands. Their return values are always boolean. The Result is Always true or false
- 24. Java has a short hand way by using ?: the ternary Operator Unlike the if statement, the conditional operator Is an expression which can be used for
- 25. boolean_expression ? expression_1 : expression_2 Any expression If true Statement If false Statement
- 27. These Operators are used to assign a values into a variable. The assignment statements has the following syntax: <variable> = <expression> Eg: a = 10;
