    Default Beginner Java code problems

    Hey guys, I am a beginner to Java and have written a code to compare two students GPA, SAT and ACT Score to say which one is wrong with my code. Here is what I have so far, does anybody see what im doing wrong? Any help would be greatly appreciated, thanks!

     
     
    import java.util.*;
     
    public class Applicants {
    	public static void main(String[] args) {
    		Scanner console = new Scanner(System.in);
     
     
    public static double grades(Scanner console) {
    	System.out.print("What is the first applicant's GPA?");
    	double GPA1 = console.nextInt();
    	System.out.print("What is the first applicant's ACT Score?");
    	int ACT1 = console.nextInt();
    	System.out.print("What is the first applicant's SAT Score?");
    	int SAT1 = console.nextInt();
     
     
    	System.out.print("What is the second applicant's GPA?");
    	double GPA2 = console.nextInt();
    	System.out.print("What is the second applicant's ACT Score?");
    	int ACT2 = console.nextInt();
    	System.out.print("What is the second applicant's SAT Score?");
    	int SAT2 = console.nextInt();
     
     
    	if (GPA1>GPA2 && SAT1>SAT2 && ACT1>ACT2) {
    		System.out.println("Applicant 1 is more qualified than Apllicant 2.");
    	} else if (GPA1<GPA2 && SAT1<SAT2 && ACT1<ACT2);
    		System.out.println("Applicant 2 is more qualified than Apllicant 1.");
    	} else if (GPA1=GPA2 && SAT1=SAT2 && ACT1=ACT2);
    		System.out.println("Applicant 1 is as equally qualified as Apllicant 2.");
    }

    Default Re: Beginner Java code problems

    else if (GPA1=GPA2 && SAT1=SAT2 && ACT1=ACT2);

    Single equals is an assignment operator. Double equals is a comparison.
    Use:
    GPA1==GPA2 instead of GPA1=GPA2 (for all the conditions in that else)

    EDIT:
    You should also not have a semicolon at the end of if statements.
