Is your program going to handle large numbers? If yes, then try thinking about ways in which your program can handle large range of numbers. One way of doing this is using a float or long variable instead of int.
The total score (or the maximum possible score); and, The obtained score whose percentage you wish to calculate. For example: If a student scores 30 marks out of 100 in a test, and you wish to calculate the percentage marks scored by the student, 100 is the total marks (or the maximum possible score). 30 is the obtained score whose percentage you wish to calculate. The formula to calculate percentage is:Percentage = (Obtained score x 100) / Total Score To get these parameters (inputs) from the user, try using the Scanner function in Java.
For example: If a student scores 30 marks out of 100 in a test, and you wish to calculate the percentage marks scored by the student, 100 is the total marks (or the maximum possible score). 30 is the obtained score whose percentage you wish to calculate.
This is because, the float data-type is 32 bit single precision that even considers decimals in mathematical calculations. Thus, using a float variable, the answer for a mathematical calculation like 5 / 2 (5 divided by 2) will be 2. 5 If the same calculation (5 / 2) if done using an int variable, the answer will be 2. However, the variables in which you stored the total score and obtained score can be int. Using a float variable for the percentage will automatically convert the int to float; and the total calculation will be done in float instead of int.
