3 Write the java Program to demonstrate the use of If else-if ladder. And display student grading as fail, D grade, C grade, B grade, A grade and A+.

Code:

public class IfElseIfExample
{
public static void main(String[] args)
{
int marks=65;

if(marks<50)
{
System.out.println("fail");
}
else if(marks>=50 && marks<60)
{
System.out.println("D grade");
}
else if(marks>=60 && marks<70)
{
System.out.println("C grade");
}
else if(marks>=70 && marks<80)
{
System.out.println("B grade");
}
else if(marks>=80 && marks<90)
{
System.out.println("A grade");
}
else if(marks>=90 && marks<100)
{
System.out.println("A+ grade");
}
else
{
System.out.println("Invalid!");
}
}
}
