Write a Java program to input marks of five subjects Physics, Chemistry, Biology, Mathematics and Computer

Input marks of five subjects and calculate the grade

Physics, Chemistry, Biology, Mathematics and Computer. Calculate percentage and grade according to following:

• Percentage >= 80% : Grade A+
• Percentage >= 75% : Grade A
• Percentage >= 70% : Grade A-
• Percentage >= 65% : Grade B+
• Percentage >= 60% : Grade B
• Percentage >= 55% : Grade B-
• Percentage >= 50% : Grade C+
• Percentage >= 45% : Grade C
• Percentage >= 40% : Grade D
• Percentage < 40% : Grade F

Sample Output

Input marks of five subjects and calculate the grade.

Physics: 87
Chemistry: 98
Biology: 71
Mathematics: 80
Computer: 85
Grade A+
