Question

The following code is not compiling in Java:

java version “1.6.0_24”
OpenJDK Runtime Environment (IcedTea6 1.11.1) (suse-3.1-x86_64)
OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)

public class XOR
{
    public static void main(String[] args)
    {
        long one = 595082963178094600000L;
    }
}

This throws the error:

XOR.java:5: integer number too large: 595082963178094600000

But I’ve properly indicated it as a long! The following also throws an error:

public class XOR
{
    public static void main(String[] args)
    {
        long one = new Long( "595082963178094600000" );
    }
}

This throws:

java.lang.NumberFormatException: For input string: "595082963178094600000"

What am I doing wrong?

Answer 1

Well, maybe because it is too large?

595082963178094600000  //your value
  9223372036854775807  //Long.MAX_VALUE

You will need either BigInteger or BigDecimal:

new BigInteger("595082963178094600000")
