Question

In Java, + can be used with integers as well as with strings. True or False?

Answer 1

"+" operator can be used with integers as well as strings in Java. When we use + for integers then it adds two integer values and when we use + for strings it concatenate two strings.

So consider the below example here we are using + to concatenate two strings s1 and s2 and save the result into s3.

Run Debug Stop e Share A Save {}Beautify Language Java Main.java 1 public class Main 2 -{ public static void main(String[] args) BOOO vouw String s1="apple"; String s2="juice"; String s3 = 1+ " "+S2; System.out.println(53); input apple juice ... Program finished with exit code o Press ENTER to exit console.

Similarly when we use + to add two integers example is

{} Beautify Language Java Run Debug Stop e Share A Save Main.java 1 public class Main 2 { public static void main(String[] args) int a=5; int b=6; int C=a+b; System.out.println(c); 10 } 11 | input 11 ... Program finished with exit code o Press ENTER to exit console.
