How can I iterate over a string in Java?

Question

public static Boolean cmprStr( String s1, String s2 )
{
    // STUFF
}

I want to iterate through s1 to make sure that every character in s1 is incl

Answer 1

As I understand the question it would be.

//for each character in s1
  //if s2 does not contain character return false

//return true

for(int i = 0; i < length s1; i++){
  if(!s2.contains(String.valueOf(s1.charAt(i)))){
    return false;
  }
}
return true;

This verifies that each character in s1 is in s2. It does not confirm order, nor how many are there, and is not an equals method.

Recursive:

public static Boolean cmprStr( String s1, String s2 )
{
  if(s1.length() == 0 )
  {
    return true; 
  }
  if(!s2.contains(s1.substring(0,1)))
  {
    return false;
  }
  return cmprStr(s1.substring(1), s2);
}
