Pre and Post Decrement Operator in Java

Pre and Post Decrement Operator in Python:

Here are the implementation of Pre and Post Decrement Operator in java language:

Java

public class Main {
    public static void main(String[] args) {
        int num1 = 15, num2 = 20;
        
        int postNum = num1--; // Post Decrement
        int preNum = --num2; // Pre Decrement

        // Printing value of postNum after post decrement.
        System.out.println("postNum = " + postNum);
        System.out.println("num1 = " + num1);

        // Printing value of preNum after pre decrement.
        System.out.println("preNum = " + preNum);
        System.out.println("num2 = " + num2);
    }
}

Output

postNum = 15
num1 = 14
preNum = 19
num2 = 19

Pre and Post Decrement Operator in Programming

Pre-decrement and post-decrement are the two ways of using the decrement operator to decrement the value of a variable by 1. They can be used with numeric data type values such as int, float, double, etc. Pre-decrement and Post-decrement perform similar tasks with minor distinctions.
