How to Fix incompatible types: possible lossy conversion from double to int

To fix the incompatible types: possible lossy conversion from double to int in Java, you can either explicitly cast the double value to an int using the (int) operator or modify your program logic to use doubles instead of integers.

double doubleValue = 3.14159; 

int intValue = (int) doubleValue;

In this case, the double value 3.14159 is cast to an int, resulting in the integer value 3. Iy will convert the double value to an int value and assign it to the int variable.

Java raises the “incompatible types: possible lossy conversion from double to int” error when assigning a double value to an integer variable. This is because doubles can represent decimal values with greater precision than integers, and converting a double to int can result in a loss of precision.

A double has a fractional part, while an int is a whole number between about minus and plus 2 billion. The double values can be too large or too small for an int, and decimal values will get lost in the conversion. Hence, it is a potential lossy conversion.

Alternatively, if you need to perform arithmetic operations on decimal values with precision, you should use double or float data types instead of int. For example:

double value_1 = 3.14159;
double value_2 = 2.71828;

double result = value_1 + value_2;

Here, the double values 3.14159 and 2.71828 are added together to produce the double value 5.85987.

That’s it.
