How do I determine whether an array contains a particular value in Java?

Question

I have a String[] with values like so:

public static final String[] VALUES = new String[] {\"AB\",\"BC\",\"CD\",\"AE\"};

Given

Answer 1

You can check it by two methods

A)By converting the array into string and then check the required string by .contains method

 String a=Arrays.toString(VALUES);
    System.out.println(a.contains("AB"));
    System.out.println(a.contains("BC"));
    System.out.println(a.contains("CD"));
    System.out.println(a.contains("AE"));

B)this is a more efficent method

 Scanner s=new Scanner(System.in);


   String u=s.next();
   boolean d=true;
    for(int i=0;i
