Hello readers, in this tutorial, we will learn the Java += operator.
1. Introduction
Java programming offers Operators that are used to perform various operations in Java. In this tutorial, we’ll only cover the += operator that falls under the Compound Assignment operators’ category.
1.1 Compound assignment operators in Java
Following table list the different compound assignment operators.
| Operator | Description | Syntax | Is equivalent to? |
+= | Compound addition assignment operator | ele2 += ele1 | ele2 = ele2+ele1 |
-= | Compound subtraction assignment operator | ele2 -= ele1 | ele2 = ele2-ele1 |
*= | Compound multiplication assignment operator | ele2 *= ele1 | ele2 = ele2*ele1 |
/= | Compound division assignment operator | ele2 /= ele1 | ele2 = ele2/ele1 |
%= | Compound modulo assignment operator | ele2 %= ele1 | ele2 = ele2%ele1 |
To start with the captioned tutorial, we are hoping that users at present have their preferred Ide installed on their machines. For easy usage, I am using Eclipse Ide on a Windows operating system.
2. Basic Operators – Java += Operator
In this example, we’ll demonstrate the += operator in java. For a better understanding, developers can execute the below code in Eclipse Ide.
Example.java
01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 | package com.example;public class Example { // Basic operators - Java += Operator. public static void main(String[] args) { int ele1 = 5; int ele2 = 5; ele2 += ele1; // ele2 += ele1 is equal to ele2 = ele2+ele1; System.out.println("+= Output is: "+ ele2);String str1 = "Java"; String str2 = "Geek"; str2 += str1; // str2 += str1 is equal to str2 = str2+str1; System.out.println("+= Output is: "+ str2); }} |
If everything goes well, the following output will be printed in the Ide console.
Output
1 2 3 | += Output: 10+= Output: GeekJava |
That is all for this tutorial and I hope the article served you whatever you were looking for. Happy Learning and do not forget to share!
3. Java += Operator – Summary
In this tutorial, we learned the += operator in Java. Developers can download the sample application as an Eclipse project in the Downloads section.
