The instanceof operator compares an object to a specified type. You can use it to test if an object is an instance of Appendix A: Operator Precedence in Java. Java has well-defined rules for specifying the order in which the operators in an expression are evaluated when the expression has several operators. For example, multiplication and division have a higher precedence than addition and subtraction. Precedence rules can be overridden by explicit parentheses. The operands to the logical OR operator don't have to have the same type, but they must be of boolean, integral, or pointer type. The operands are commonly relational or equality expressions.

2020-11-01 · || is a type of Logical Operator and is read as “OR OR” or “Logical OR“. This operator is used to perform “logical OR” operation, i.e. the function similar to OR gate in digital electronics.

The Bitwise Operators. Java defines several bitwise operators, which can be applied to the integer types, long, int, short, char, and byte. Bitwise operator works on bits and performs bit-by-bit operation. Assume if a = 60 and b = 13; now in binary format they will be as follows −. a = 0011 1100. b = 0000 1101-----a&b = 0000 1100

For Example, Java Operators. Operators are used to perform operations on variables and values. In the example below, we use the + operator to add together two values: Java provides a rich set of operators to manipulate variables. We can divide all the Java operators into the following groups − Arithmetic Operators; Relational Operators; Bitwise Operators; Logical Operators; Assignment Operators; Misc Operators; The Arithmetic Operators Operators are special symbols that perform specific operations on one, two, or three operands, and then return a result. As we explore the operators of the Java programming language, it may be helpful for you to know ahead of time which operators have the highest precedence. When both operands of a &, ^, or | operator are of type boolean or Boolean, then the type of the bitwise operator expression is boolean. As Rob pointed out, the difference is that the || is conditional, in that the right operand is evaluated only if the left operand evaluates to false.
