Java Program to construct one String from another

To construct on string from another, firstly take a charcter array for the first string.

char ch[] = { 'A', 'M', 'I', 'T' }; String str1 = new String(ch);

The above forms first string. Now, let us created another string from the first string.

String str2 = new String(str1);

In this way, we can easily construct one string from another.

Example

 Live Demo

public class Demo {    public static void main(String[] args) {       char ch[] = { 'A', 'M', 'I', 'T' };       String str1 = new String(ch);       String str2 = new String(str1);       String str3 = new String(str2);       System.out.println("String 1: "+str1);       System.out.println("String 2: "+str2);       System.out.println("String 3: "+str3);    } }

Output

String 1: AMIT String 2: AMIT String 3: AMIT
