    y = input.nextLine();

    String x;
    System.out.println("Please input how many times you want '" + y + "' to be repeated, lord " + z + ": ");

    Welcome! Please read this topic to learn how to post code correctly and other useful info for new members.

    Please ask specific questions. Describe the program's existing behavior, the desired behavior, and post errors and sample runs that show the problem(s) you want help with, both copied and pasted from exactly as they appear at your end.

    Here it is:
    package loopquestion;
     
    import java.util.Scanner;
     
    public class LoopQuestion {
    public static void main(String[] args) 
    {
    {
    Scanner input = new Scanner (System.in);
    String z;
    System.out.println("What is your name?");
     
    z = input.nextLine();
     
    String y;
    System.out.println("What is your phrase?");
     
    y = input.nextLine();
     
    String x;
    System.out.println("Please input how many times you want '" + y + "' to be repeated, lord " + z + ": ");
     
     
    System.out.println(y * x);
    }
     
    }

    And a nextLine() as you have done is ok.

    You need an int value here, not a String. You can get an int directly from Scanner or you can get another String and then "parse" it into an int (see parseInt method of Integer). At your choice.

    You need to do a "loop". If you don't know what are loops .... please, study, starting for example at Control Flow Statements (The Java™ Tutorials > Learning the Java Language > Language Basics)


    And please, give "good" names to variables ..... not x y etc... that are very "ugly".

    Use a variable name that describes what the variable contains.
    If you don't understand my answer, don't ignore it, ask a question.

    A for loop is a normal loop. When you know how many times the loop should execute, the for loop is the natural choice. If looping is dependent on the results of the loop body, then a do/while or while loop might be more appropriate. The do/while assures the body of the loop will execute at least once. The while loop does not give the same guarantee.
