Question

String s1 is said to overlap String s2 if all of the characters in s1 also appear in s2. Write a set of code that will set the boolean variable overlap to true if s1 overlaps s2 and false otherwise. Assume both s1 and s2 have already been input.

Answer 1

public class Main
{
   public static void main(String[] args) {
       String s1="Hello World";
       String s2="oWl";
       boolean overlap=true;
       for(int i=0;i<s2.length();i++)
       {
       char ch=s2.charAt(i);//take character
       int f=0;
       for(int j=0;j<s1.length();j++)
       {
       //search if it is present in s1
       if(ch==s1.charAt(j))
       {
       f=1;//if it is present search for next
       break;
       }
       }
       if(f==0)//if not found make it false
       {
       overlap=false;
       break;
       }
      
       }
       if(overlap)
       {
       System.out.println("overlaps");
       }
       else
       {
       System.out.println("Does Not overlaps");
       }
   }
}

overlaps
