Java Operator Precedence and Associativity

Operator associativity (Right to Left) The assignment(=) operators are also typically ‘right to left’ associative. Program Program Source public class Javaapp { public static void main(String[] args) { int a,b,c,d; a=b=c=d=10; System.out.println(“a = “+a); System.out.println(“b = “+b); System.out.println(“c = “+c); System.out.println(“d = “+d); } }

Operator Associativity The operators of the same precedence are evaluated either from ‘left to right’ or ‘right to left’, depending on the level. This is known as the associativity property of an operator. Operators Associativity ( ) [ ] . Left to Right ++ – – ~ ! Right to Left * / % Left … Read more…

Force Precedence Parentheses( ) may be used to force precedence, if necessary. For example : int totel=5*(5+15)/2; Generally multiplication and division operation has a higher precedence than the addition operation. But, addition operation executing first. Because, addition operation covered by parentheses. Parentheses may be used to force precedence, if necessary. Program Program Source public class Javaapp { public … Read more…

Operator Precedence Operator precedence is used to determine how an expression involving more than one operator is evaluated. There are distinct levels of precedence and an operator may belong to one of these levels. The operators at the higher level of precedence are evaluated first. Operators Precedence Levels ( ) [ ] . 1 ++ … Read more…
