How to check if a value coincide with any enum value?

I want to detect if a input values of a vector coincide with any value of a enum, I just got what detect if are entered in order, but I don't mind the order. (The same order what I declared the enum values). ```java import java.util.Scanner; public class EnumsNames{ Scanner key=new Scanner(System.in); public void ENames(){ enum Names{ Alejandra,Leonardo,Rosa,Guillermo,Gabriel,Daniel,Luisa,Ludmila } String[] name=new String[8]; for(int n=0;n<name.length;n++){ boolean valid=false; while(!valid){ System.out.println("Input a name:"); name[n]=key.next(); // In this if are my problem if(name[n].equals(Names.values()[n].toString())){ valid=true; }else{ System.out.println("Invalid name"); } } } }

So baiscally you have a string and want the enum value of it if there is one like this

String example = "Alejandra";

String example = "Alejandra";

and then you want the enum value of the string

Names name = Names.valueOf(example);

Names name = Names.valueOf(example);

there you go method

public Names getEnumValue(String input)
{
    Names name = Names.valueOf(input);
    if(name == null)
    {
        System.out.println("Invalid name");
        return null;
    }
    else
    {
        System.out.println("Valid name");
        return name;
    }
}

public Names getEnumValue(String input)
{
    Names name = Names.valueOf(input);
    if(name == null)
    {
        System.out.println("Invalid name");
        return null;
    }
    else
    {
        System.out.println("Valid name");
        return name;
    }
}

is also equal to

public Names getEnumValue(String input)
{
    Names name = Names.valueOf(input);
    if(name == null)
    {
        System.out.println("Invalid name");
    }
    else
    {
        System.out.println("Valid name");
    }
    return name;
}

public Names getEnumValue(String input)
{
    Names name = Names.valueOf(input);
    if(name == null)
    {
        System.out.println("Invalid name");
    }
    else
    {
        System.out.println("Valid name");
    }
    return name;
}

So, In Names.valueOf(input); "input" would be the vector in my case?
