Why am I getting an "Integer Number Too Large" Error in Java?

Integer Range Error in Java: Understanding "Integer Number Too Large"

When executing the code provided, an error message is encountered at the line obj.function(600851475143);. This error is attributed to the attempt to represent the large numerical value 600851475143 as a 32-bit integer (type int) within the Java programming language.

In Java, numbers without a suffix are inherently integers, capable of representing only values within a specific range (-2^31 to 2^31 - 1). However, the range of numbers that can be handled as integers is often insufficient for practical applications.

To overcome this limitation, Java introduces the long data type, which extends the integer range to 64 bits. This allows for much larger values to be stored and processed. To indicate a long literal in Java code, the integer suffix "L" must be appended, as exemplified by 600851475143L.

By modifying the problematic line to obj.function(600851475143L), we rectify the issue and enable the code to process the large numerical value accurately, resolving the "Integer number too large" error.
