043 - Method Header Practice 8

Write a method header on line two with the following specs:

 

Returns: a String

Name: makeThreeSubstr

Parameters:

• a String called "word"

• an integer called "startIndex"

• an integer called "endIndex"

 

Then, starting on line 4, write code that will return 3x the substring (no spaces) from "startIndex" to "endIndex"

 

Examples:

• makeThreeSubstr("hello",0,2) ==> "hehehe"

• makeThreeSubstr("shenanigans",3,7) ==> "naninaninani"

import java.util.*;
class Main {
    public static String makeThreeSubstr(String word, int startIndex, int endIndex)
    {
        String temp="";
        for(int i=0;i<3;i++) {
            temp+=word.substring(startIndex,endIndex);
        }
        
        return temp;
    }
    
    //test case below (dont change):
    public static void main(String[] args){
        System.out.println(makeThreeSubstr("hello",0,2)); //should be hehehe
        System.out.println(makeThreeSubstr("shenanigans",3,7)); //should be naninaninani
    }
}
