Some help with boolean

Hello guys,

I'm totally new to Java and I seek some help with this thing.
I know it is too easy for you, but it's not the same for me as I'm playing with Java for 2 months only.

I have this part of the code:

Code Java:

---

public boolean setPercentages(int A, int B) {
    A = console.nextInt();
    B = console.nextInt();
 
if (A + B == 100) {
    return true;
}
else {
    return false;    
}

---

I want to correct this code so that if the integers sum equals 100, then it returns "true" as well as the method assigns them to courseworkPercentage and examPercentage respectively, otherwise the program
must return false.

I'm confused now and I can not think a simple solution.
Could you help me?

Peter

What are courseworkPercentage and examPercentage? Where are they defined with respect to this function?

Sorry! Here's my code so far.....it's not that big so maybe you could help me :cool:

Code Java:

import java.util.*;
 
public class StudentInGradeBook {
    String lastName, firstName;
    int studentId;
    double courseworkGrade, examGrade, Grade;
    static double courseworkPercentage, examPercentage;
 
public StudentInGradeBook (int I, String L, String F) {
    studentId = I;
    lastName = L;
    firstName = F;
}
 
public StudentInGradeBook() {
    studentId = 0;
    lastName = "Not defined";
    firstName = "Not defined";
}
 
public void setCourseworkGrade (double courseworkGrade) {
    courseworkGrade = courseworkGrade;    
}
 
public void setExamGrade (double examGrade) {
    examGrade = examGrade;
}
 
public int getStudentId() {
    return studentId;
}
 
public String getLastName() {
    return lastName;
}
 
public String getFirstName() {
    return firstName;
}
 
public double getCourseworkGrade() {
    return courseworkGrade;
}
 
public double getExamGrade() {
    return examGrade;
}
 
public double getGrade() {
    return Grade;
}
 
public double getCourseworkPercentage() {
    return courseworkPercentage;
}
 
public double getExamPercentage() {
    return examPercentage;
}
 
public double calcGrade;{
    Grade = (courseworkGrade * courseworkPercentage/100) + (examGrade * examPercentage/100);
}
 
    static Scanner console = new Scanner(System.in);   
 
public boolean setPercentages(int A, int B) {
    A = console.nextInt();
    B = console.nextInt();
 
if (A + B == 100) {
    return true;
}
else {
    return false;    
}
 
 
}
}

First, a question for you. Why are courseworkPercentage and examPercentage declared static? Do you really want them to have the same value for all instances of the class?
