Operators in Java are special symbols to perform specific tasks on operands. Operators can be classified into the following types: arithmetical, relational, increment/ decrement, logical and assignment.
Arithmetic operators are used to perform arithmetic operations, such as addition subtraction and multiplication. The arithmetic operators are of two types: unary operators and binary operators. The relational operators are used to compare two values and determine the relationship between them. The increment operator (++) adds 1 to operand’s value. The decrement operator (--) subtracts 1 from operand’s value. The logical operators are used to evaluate multiple conditions together as a single expression. The assignment operator is used to update the value of a variable.
