Java String: Exercise-77 with Solution
Write a Java program to add a string with specific number of times separated by a substring.
Sample Solution:
Java Code:
import java.util.*;
public class Main
{
public String addBySeparator(String main_str, String sep_str, int ctr)
{
String new_word = "";
for (int i = 0; i < ctr; i++)
{
if (i < ctr-1)
new_word += main_str + sep_str;
else
new_word += main_str;
}
return new_word;
}
public static void main (String[] args)
{
Main m= new Main();
String str1 = "try";
String str2 = "best";
int ctr=3;
System.out.println("The given strings are: "+str1+" and "+str2);
System.out.println("Number to times to be repeat: "+ctr);
System.out.println("The new string is: "+m.addBySeparator(str1,str2,ctr));
}
}
Sample Output:
The given strings are: try and best Number to times to be repeat: 3 The new string is: trybesttrybesttry
