    Default Difficulty calling method in another method

    Hi, first time on here so hope i am in the right place. I have created the methods gradeTemp and getValidTemp, which i can run independently. However when i attempt to call them both in tempGrading i cannot. To be clear what I am trying to do in tempGrading method is call getValid temp to provide me with a temp for which I can then call gradeTemp to give a rating. In addition to the code below I have tried including in tempGrading: vTemp= temp; rating=gradeTemp(vTemp); but cant make work in either case.

    import java.util.*;

    public class Temperature
    {


    static void gradeTemp() {

    int temp;



    Scanner sc=new Scanner(System.in);
    System.out.println("Enter temperature");

    temp = sc.nextInt();
    System.out.print("The temp is ");
    if(temp>=70 && temp<=100) {
    System.out.println("Very Hot");
    } else if (temp>=60 && temp<=69) {
    System.out.println("Hot");
    }
    else if (temp>=50 && temp<=59) {
    System.out.println("Warm");}
    else if (temp>=40 && temp<=49) {
    System.out.println("Cool");}
    else if (temp>=0 && temp<=39) {
    System.out.println("Cold");}


    }
    public static int getValidTemp() {
    Scanner sc=new Scanner(System.in);
    int temp;
    System.out.println ("Enter a Temperature in range 0 to 100");
    mark=sc.nextInt();
    while (temp < 0 || temp > 100)
    {
    System.out.println("Invalid temperature !");
    System.out.println ("Enter a mark in range 0 to 100");
    mark=sc.nextInt();
    }
    return mark;}

    public void tempGrading() {
    Scanner sc=new Scanner(System.in);
    char response;
    int temp, vTemp;

    System.out.println("*********** Temperature Grading *********");
    System.out.println("Enter temperature to receive rating");


    do {
    String rating;
    temp = getValidTemp();
    rating= gradeTemp();
    System.out.println("Your rating is" + rating);

    System.out.print("another go (y/n)? =>");
    response = sc.next().charAt(0);
    } while (response == 'y'|| response =='Y');
    }
    }

    Thanks for your response, I have now resolved, my error was declaring formal parameters.
