Why Does My Java Code Throw an "Integer Number Too Large" Error for 600851475143?

Error Message: "Integer Number Too Large" for 600851475143

The provided Java code aims to find the largest prime factor of a given number. However, when running the code for the input 600851475143, it throws an error. This error is caused by the fact that Java represents integers as 32-bit numbers by default. As a result, the number 600851475143, which exceeds the maximum value of a 32-bit integer, cannot be accommodated within this range.

To resolve this issue, we can use Java's long data type, which represents 64-bit integers and can handle larger numerical values. In the given code, simply replace the declaration of the input number with the following:

obj.function(600851475143L);

By appending an "L" at the end of the number, we specify it as a long literal. This ensures that Java represents the number as a 64-bit integer, avoiding the "Integer number too large" error.
