I have the following code:

public class String verifyWord(String wordChosen, Scanner reader){ //linha 1
    boolean answeredCorrectly = false;
    int tries = 1;
    String wordChosen = random.nextInt();
    String answer = wordChosen;

    while(tries>0 && answeredCorrectly == false) { //linha 6
        answer = reader.nextInt();

        if(wordChosen == answeredCorrectly) {
            System.out.println("You got it right");
            answeredCorrectly=true;
        }
        else if(answered =! wordChosen){
            System.out.println("Wrong");
        }
    }

}

In the first line according to the program there is an error, after String says that I must for a { key, but I believe this is not the solution. In line 6 in while the program says:

"illegal start of type". ~

I started very little time and I do not understand how to solve these errors.

First you create the class and then create the method, then it would look something like this:

public class AlgumNomeAqui {
    public String verifyWord(String wordChosen, Scanner reader){
        boolean answeredCorrectly = false;
        int tries = 1;
        String wordChosen = random.nextInt();
        String answer = wordChosen;
        while (tries>0 && !answeredCorrectly) {
            answer = reader.nextInt();
            if (wordChosen == answeredCorrectly) {
                System.out.println("You got it right");
                answeredCorrectly = true;
            }
            else if (answered != wordChosen) {
                System.out.println("Wrong");
            }
        }
    }
}

Obviously a class should not be that simple. I solved the problem reported in the question, but it is far from really addressing the issue. You still have flooring to understand how to create a class.

There are cases that even a class is not really needed. Since Java requires classes, it can be static if you only have one utility method.

I had other errors. Try to learn in a structured way, one step at a time, the basics of syntax, the imperative, and then do more advanced things. If you do not understand what each character does in the code you are not actually programming.

You've mixed class creation with method creation.

First create the class:

public class NomeDaClasse {
}

and the method you can put inside the class:

public String verifyWord(String wordChosen, Scanner reader)
{
    ...
}

Your method has very strange logic, for example:

Returns as string but is not returning anything.

You are using the Random.nextInt() function that returns a inteiro , and assigning a variable string .

Finally, a code review, first of all, to avoid future problems.
