Answer 1

public class JavaApplication78 {

   public boolean findChar(String string, String key){

       if (string.contains(key)){

           return true;

       }

      return false;

   }

   public static void main(String[] args) {

       JavaApplication78 java = new JavaApplication78();

       System.out.println(java.findChar("hello", "h"));

   }

   

}

First I created the findChar method using the contains method. It checks to see if a certain sequence of characters is in another string. We returned the result. In our main method, we had to create a new instance of our main class so we could call our findChar method.
