Percentage Calculator

This Java program calculates the percentage of obtained marks based on different scenarios: 4 core subjects, 5 subjects, 6 subjects, and the top 5 subjects in a 6-subject scenario. The user provides the maximum marks (either 400, 500, or 600) and the obtained marks for each subject. The program then calculates and displays the appropriate percentages.

• Calculates the percentage for all 5 subjects if the maximum marks are 500.
• Calculates the percentage for all 6 subjects and the top 5 subjects if the maximum marks are 600.
