Question
Can someone help me please figure out this problem i thought i had it but it has an error in line 60...my project was to write an application to be used in a college admission's office. To be admitted to this school, the student must have either:•A grade point average of 3.0 or higher and an entrance score of 60 or higher
•An entrance score of 85 or higher and any grade point average
To make things more user friendly, write some code to do some error checking of the data. That is, if the grade point average is not between 0.0 and 4.0 or if the entrance score is not between 0 and 100, then print an appropriate error message to the screen telling the user that they entered invalid data.
Use the above criteria to write a procedure called, accepted, that takes the grade point average and entrance score as parameters and returns no value. This procedure will print either "Accept" or "Reject", accordingly.
Finally, write a main procedure that prompts the user for a grade point average and an entrance score. This procedure should then call the accepted method to display the result.
Although your output is not required to look this way, sample output from your program may look something like:
Welcome to the Admissions Department.
Please enter your grade point average: 2.9
Please enter your entrance score: 86
We are pleased to accept you at our school.
Running the program a second time, might look like:
Welcome to the Admissions Department.
Please enter your grade point average: 2.9
Please enter your entrance score: 115
You have entered an invalid value.
Here is the code for the program can you help?
import java.util.Scanner;
public class Admission
{
public static void main(String[] args)
{
// input
Scanner kb = new Scanner(System.in);
double gpa = -1;
while(true)
{
System.out.print("Enter the gpa: ");
try
{
gpa = kb.nextDouble();
}
catch(Exception ex)
{
System.out.println("Invalid GPA.");
}
if(gpa < 0.0 || gpa > 4.0)
{
System.out.println("Invalid GPA.");
}
else
{
break;
}
}
int score = -1;
while(true)
{
System.out.print("Enter the entrance exam score: ");
try
{
score = kb.nextInt();
}
catch(Exception ex)
{
System.out.println("Invalid score.");
}
if(score < 0 || score > 100)
{
System.out.println("Invalid score.");
}
else
{
break;
}
}
accepted(gpa, score);
}
public void accepted(double gpa, int score)
{
if(gpa >= 3.0 || score >= 60)
{
System.out.println("Accept");
}
else
{
System.out.println("Reject");
}
}
}
Explanation / Answer
please rate - thanks
changes I made are in red
import java.util.Scanner;
public class Admission
{
public static void main(String[] args)
{
// input
Scanner kb = new Scanner(System.in);
double gpa = -1;
while(true)
{
System.out.print("Enter the gpa: ");
try
{
gpa = kb.nextDouble();
}
catch(Exception ex)
{
System.out.println("Invalid GPA.");
}
if(gpa < 0.0 || gpa > 4.0)
{
System.out.println("Invalid GPA.");
}
else
{
break;
}
}
int score = -1;
while(true)
{
System.out.print("Enter the entrance exam score: ");
try
{
score = kb.nextInt();
}
catch(Exception ex)
{
System.out.println("Invalid score.");
}
if(score < 0 || score > 100)
{
System.out.println("Invalid score.");
}
else
{
break;
}
}
accepted(gpa, score);
}
public static void accepted(double gpa, int score)
{
if((gpa >= 3.0 && score >= 60)||score>85)
{
System.out.println("Accept");
}
else
{
System.out.println("Reject");
}
}
}
