    edit:

    I deleted it by accident lol, here it is again:

    import java.io.*;
    import java.util.*;
     
     
    public class ConvertString {
     
    public static void main(String args[]) {
     
    String input = "";
    int number = 0;
    Scanner key = new Scanner(System.in);
     
    System.out.println("Enter a number");
    input = key.next();
     
    //CompareTo function
    if(input.compareToIgnoreCase("two")==0) {
    	number = 2;
    	System.out.println(number);
    }
     
    //equals function
    else if(input.equals("three")) {
    	number = 3;
    	System.out.println(number);
    }
     
     
     
    }
    }
