My assignment is this:

Create a Java program that satisfies the following requirements:

• Create a single Java source file named MaxScore.java
• Create a single class named MaxScore
• The MaxScore class has two methods:
  • main
  • maxScore

The maxScore method takes seven integer arguments When called, the maxScore method returns the largest of the seven input arguments

The main method performs the following steps seven times:

• Write to STDOUT: Enter a score:
• Read from STDIN an integer value and store it in a new variable
• The main method calls maxScore with the seven integers obtained from STDIN
• The main method writes to STDOUT the maximum score in the following format: Maximum score is:

My main problem is that the symbol is not defined. I have tried this a bunch of times with no luck. I'm sure it's a fairly easy to fix problem but I could really appreciate some help. Here is my code:

    import java.util.Scanner;

    public class MaxScore1{
public static void main(String[] args){ 
//establishes the main method first
int z = a,b,c,d,e,f,g; 

    z = maxScore(a,b,c,d,e,f,g); 

    Scanner foo = new Scanner( System.in ); 
    //repeating the code 7 times in order to get 7 integers that are the scores
    System.out.print("Enter a score: ");
    a = foo.nextInt();
    System.out.print("Enter a score: ");
    b = foo.nextInt();
    System.out.print("Enter a score: ");
    c = foo.nextInt();
    System.out.print("Enter a score: ");
    d = foo.nextInt();
    System.out.print("Enter a score: ");
    e = foo.nextInt();
    System.out.print("Enter a score: ");
    f = foo.nextInt();
    System.out.print("Enter a score: ");
    g = foo.nextInt();
    System.out.println("Maximum value returned by maxScore is " + z + "."); 

    }
public static int maxScore(int a,int b,int c,int d,int e,int f,int g){ 
//calling all the integers obtained earlier
    int x; 
    //establishing a base for the currentscore
    x = 0;
    //establishing the variable
    if (a > x){ 
    //a set of if statements to return the maximum value
        x = a;
        }
    if (b > x){
        x = b;
        }
    if (c > x){
        x = c;
        }
    if (d > x){
        x = d;
        }
    if (e > x){
        x = e;
        }
    if (f > x){
        x = f;
        }
    if (g > x){
        x = g;
        }
    return x; //returning the maximum value obtained.
    }

}

My errors are:

Answer 1

You should declare your variables correctly int z,a,b,c,d,e,f,g; and calculate the max score only after you read in all the values.

Answer 2

Please declare your variables like this int a,b,c,d,e,f,g; Not in the way that you did it already.
