Java Basic Operators

Java Basic Operations

Java supports the following operations on variables:

• Arithmetic : Addition(+), Subtraction(-), Multiplication(*), Division(/), Modulus(%),Increment(++), Decrement(--).
• String concatenation: + can be used for String concatenation but subtraction - on a String is not a valid operation.
• Relational: Equal to(==), Not Equal to (!=), Greater than(>), Less than(<), Greater than or equal to(>=), Less than or equal to(<=),
• Bitwise: Bitwise And(&), Bitwise Or(|), Bitwise XOR(^), Bitwise Compliment(~), Left shift(<<), Right Shift (>>), Zero fill right shift (>>>)
• Logical: Logical And (&&), Logical Or(||), Logical Not (!)
• Assignment: =, +=, -=, *=, /=, %=, <<=, >>=, &=, ^=, |=
• Others: Conditional/Ternary(?:), instanceof

While most of the operations are self explanatory, the Conditional (Ternary) Operator works as follows:

expression that results in boolean output ? return this value if true : return this value if false

For e.g:

int x = 10;
int y = (x == 10) ? 5 : 9; <-- y will equal 5 since the expression x == 10 evaluates to true
