Error: Else without If, and ";" Expected in Nested If Statement

I am trying to create a program wherein the program will generate a random number between 0 and 100, and depending on the range, will assign the equivalent Letter Grade to it. I have my If and Else if statements already laid out, but I am getting the following errors on the "else if" lines:

illegal start of type

‘;’ expected

‘else’ without ‘if’

I have tried adjusting the locations of the brackets based on how other people have done their nested if Java code online, and even removed the semi-colon.

Code is below:

public class StudentGrade 
{
    public static void main(String[] args)
    {   
        for (int i = 0; i<5; i++)
        { 
            int grade = (int)(Math.random() * 50) + 50;
            if (grade > 0 && grade < 53)
            {
                System.out.println("Student grade is " + grade + " which is F.");
            }
            else if( grade >= 53 && < 74)
            {
                System.out.println("Student grade is " + grade + " which is C.");
            }
            else if (grade >= 74 && < 83)
            {
                System.out.println("Student grade is " + grade + " which is B.");
            }
            else if (grade >= 83 && < 89)
            {
                System.out.println("Student grade is " + grade + " which is B.");
            }
            else if (grade >= 89 && < 100)
            {
                System.out.println("Student grade is " + grade + " which is A.");
            }
        }
    }
}

>Solution :

your if statement syntax was wrong.

if( grade >= 53 && < 74)

if your if statements means grade between 53 to 74. then maybe if statement can be like this:

if ( grade >= 53 && grade < 74 )

and this is more infomation for java if statements
