Program Description<\/h3>\n

Write a java program to demo the decrement operator. We will look at a simple java program using the decrement operator. We will have a look at the postfix-decrement operation and prefix-decrement operation in the program.<\/p>\n

Syntax<\/h3>\n

– – Decrement operator: decrements the variable value by 1<\/strong><\/p>\n

Postfix decrement<\/h3>\n

b=a–;<\/p>\n

Prefix decrement<\/h3>\n

b= –a;<\/p>\n

Java Program<\/h3>\n
\/\/ DecrementOperatorDemo.java program\r\npublic class DecrementOperatorDemo {\r\n\r\n  public static void main(String[] args) {\r\n    int a = 4; \r\n    a--; \r\n\r\n    \/\/print the variable\r\n    System.out.println(\"a after Decrement should print 3= \" + a);\r\n\r\n    int b;\r\n    b= a--;\/\/ a is assigned to b and then decremented\r\n\r\n    \/\/print the variable\r\n    System.out.println(\"b after post decrement should print 3= \" + b);\r\n    \/\/ a value is 2 now\r\n    b= --a;\/\/ a value is decremented and assigned to b\r\n    \/\/print the variable\r\n    System.out.println(\"b after pre decrement should print 1= \" + b);\r\n  } \r\n}\r\n<\/pre>\n
 <\/p>\n
Program Output<\/h3>\n
a after Decrement should print 3= 3
\nb after post decrement should print 3= 3
\nb after pre decrement should print 1= 1<\/p>\n
