Why Does Integer Division in Java Result in 0.0, and How Can I Fix It?

Division of Integers Coerced to 0.0 in Java

When dividing two integers in Java, the result is cast to an integer, leading to the conversion of the result to 0.0 if both integers are positive. To resolve this issue, consider converting one or both integers to a floating-point type before performing the division.

In your specific code:

int totalOptCount = 500;
int totalRespCount=1500; 
float percentage =(float)(totalOptCount/totalRespCount);

To obtain the correct result, you should explicitly cast one of the operands to a float:

float percentage = ((float) totalOptCount) / totalRespCount;

Optionally, you may format the result to the desired precision and convert it to a string:

String str = String.format("%2.02f", percentage);
