Question :-
2. Write a program to compute grade of students using if else ladder. The grades are assigned as followed:
a. Marks Grade
b. marks<50 F
c. 50<marks< 60 C
d. 60<marks<70 B
e. 70<marks<80 B+
f. 80<marks<90 A
g. 90<marks< 100 A+
3. Write a program to check whether a date is valid or not.
Answer :-
i.) Program -
import java.util.Scanner; \\importing package
class ad \\class declaration
{
public static void main(String args[]) \\main()method declaration
{
System.out.println("Enter the marks");
int n; \\input object declaration
Scanner sc=new Scanner(System.in); \\input object creation
n = sc.nextInt();
if(n<50)
{
System.out.println("F");
}
else if(n>50 && n<60)
{
System.out.println("C");
}
else if(n>60 && n<70)
{
System.out.println("B");
}
else if(n>70 && n<80)
{
System.out.println("B+");
}
else if(n>80 && n<90)
{
System.out.println("A");
}
else if(n>90 && n<100)
{
System.out.println("A+");
}
}
}
