Answer 1

import java.util.stream.Collectors;
import java.util.stream.Stream;

public class MyClass {
    public static void main(String[] args)
    {
        String str1 = "AFC";
        String str2 = "DEB";
        String str3 = "AECBFD";
        
        String str1str2 =  Stream.of((str1 + str2).split(""))
                    .sorted()
                    .collect(Collectors.joining());
        
        str3 =  Stream.of(str3.split(""))
                    .sorted()
                    .collect(Collectors.joining());

        System.out.println(str1str2);
        System.out.println(str3);
        
        if (str1str2.equals(str3)) {
            System.out.print("yes");
        }
        else {
            System.out.print("no");
        }
    }
}
