The example demonstrates how to declare multiple variables in a loop by java declaration block.
Source Code
package com.beginner.examples;
import java.util.Arrays;
public class DeclareMultipleMariablesInLoopExample {
public static void main(String[] args) {
String test = "Hello world!";
char[] chs = test.toCharArray();
//Declare multiple variables in a loop
for(int start=0,end=chs.length-1;start<end;start++,end--)
{
//Switch heads and tails
char temp = chs[start];
chs[start] = chs[end];
chs[end]=temp;
}
System.out.println(Arrays.toString(chs));
}
}
Output:
[!, d, l, r, o, w, , o, l, l, e, H]
