Operators
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. Operations are represented by
operators. The objects of operations are referred to as operands. Operators can be unary, binary or ternary. When an integer and a floating point number are used as operands to a single arithmetic operation, the result is a floating point. The integer is implicitly converted to a floating point number before the operation takes place. Unary increment operator (+ +) increases the value of an operand by 1.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. Relational operators have lower precedence than that of arithmetic operators. Logical operator ( ! ) has precedence higher than that of any of the relational or arithmetic operator.
