Question:

How to test if an Array contains a certain value?

Answer:

Iterate through the array looking for a match

Or

Convert array to a list and use the method contains()

Code:

import java.util.*;
 
public class TestArray {
   public static void main(String[] args) {
 
      String[] names = new String[] {"George","Paul","Ringo","John"};
      System.out.println(Arrays.toString(names));
 
      String who = "George";
 
      // iterate through the array looking for a match 
      for (int i = 0; i < names.length; i++){
         if(who.equals(names[i])){
            System.out.println( who + " is found");
            break;
         }
      }  
 
      // convert array to a list and use the method contains()
      List list = Arrays.asList(names);
      if(list.contains(who)){
         System.out.println( who + " is found");
      }
 
   }
}

Output:

$ java TestArray 
[George, Paul, Ringo, John]
George is found
George is found
