Introduction<\/h3>\n

In this post, we will discuss the Increment Operator in java language. We will look at some simple java program using the operator. We will have a look at the postfix-increment operation and prefix-increment operation in the program.<\/p>\n

Syntax<\/h3>\n

++ Increment operator: increments a value by 1<\/strong><\/p>\n

Postfix increment<\/h3>\n

b = a++;<\/p>\n

 <\/p>\n

Prefix increment<\/h3>\n

b = ++a;<\/p>\n

Java Program<\/h3>\n
\/\/ IncrementOperatorDemo.java program\r\npublic class IncrementOperatorDemo {\r\n\r\n  public static void main(String[] args) {\r\n    int a = 1; \r\n    a++; \r\n\r\n    \/\/print the variable\r\n    System.out.println(\"a after increment should print 2= \" + a);\r\n\r\n    int b;\r\n    b= a++;\/\/ a is assigned to b and then incremented\r\n\r\n    \/\/print the variable\r\n    System.out.println(\"b after post increment should print 2= \" + b);\r\n    \/\/ a value is 3 now\r\n    b= ++a;\/\/ a value is incremented and assigned to b\r\n    \/\/print the variable\r\n    System.out.println(\"b after pre increment should print 4= \" + b);\r\n  } \r\n}\r\n<\/pre>\n
 <\/p>\n
In the program, we have initialized two variables a & b and then increment them using the operator. We print the post incremented ++ variables a & b.<\/p>\n
Program Output<\/h3>\n
a after increment should print 2= 2
\nb after post increment should print 2= 2
\nb after pre increment should print 4= 4<\/p>\n
