Given a string and a nonnegative int n well say that the fro

Given a string and a non-negative int n, we\'ll say that the front of the string is the first 3 chars, or whatever is there if the string is less than length 3. Return n copies of the front;

frontTimes(\"Chocolate\", 2) \"ChoCho\"
frontTimes(\"Chocolate\", 3) \"ChoChoCho\"
frontTimes(\"Abc\", 3) \"AbcAbcAbc\"

Must work the following problem using a while loop or do while.

Solution

StringTimesTest.java

public class StringTimesTest {

  
   public static void main(String[] args) {
      
System.out.println(frontTimes(\"Chocolate\", 2) );
System.out.println(frontTimes(\"Chocolate\", 3) );
System.out.println(frontTimes(\"Abc\", 3) );
   }
   public static String stringTimes(String s, int n){
       String returnString = \"\";
       int i=0;
       while(i<n){
           returnString = returnString + s;
           i++;
       }
       return returnString;
   }
   public static String frontTimes(String s, int n){
       if(s.length()<=3){
           return stringTimes(s, n);
       }
       else{
           return stringTimes(s.substring(0,3), n);
       }
   }

}

Output:

ChoCho
ChoChoCho
AbcAbcAbc
