Define a class to accept two strings of same length and form a new word in such a way that, the first character of the first word is followed by the first character of the second word and so on.
Example :
Input string 1 – BALL
Input string 2 – WORD
OUTPUT : BWAOLRLD
import java.util.Scanner;
public class RansariStringMerge
{
public static void main(String args[])
{
Scanner in = new Scanner(System.in);
System.out.println("Enter String 1: ");
String s1 = in.nextLine();
System.out.println("Enter String 2: ");
String s2 = in.nextLine();
String str = "";
int len = s1.length();
if(s2.length() == len)
{
for (int i = 0; i < len; i++)
{
char ch1 = s1.charAt(i);
char ch2 = s2.charAt(i);
str = str + ch1 + ch2;
}
System.out.println(str);
}
else
{
System.out.println("Strings should be of same length");
}
}
}
First understand the algorithm carefully. Then study the program line-by-line and compare it with the output. Finally, review the explanation section to strengthen your logic and programming understanding.
Rewrite the program without looking at the code. Modify values, conditions or logic and run it again. This helps improve confidence and strengthens coding skills much faster.
