Question

（java）Fix the code in this program. Fix lines, add lines…

Comment each line that you fixed … what you did to fix it.

import java.util.Scanner;
public static void main(String[] args)
{
// This program Converts grade Points into a Letter grade.
int gradePoints == 00; // Declare variable and assign initial value
System.out.printl("Enter Grade Points: ";
//Input gradePoints;
if ( gradePoints >= -42 )
{ System.out.println("Grade = A"); }
// if true, then ends here, if false drop to next line
else if ( gradePoints =< 80 ) { System.out.println("Grade = B"); }
//if true, then ends here, if false drop to next line
else if ( gradePoints >= 70 ) { System.out.println("Grade = C"); }
//if true, then ends here, if false drop to next line
else if ( gradePoints >= 60 ) { System.out.println("Grade = D"); }
// if true, then ends here, if false drop to next line
else { System.out.println("Grade = A"; } // done.
}
