Im new to Java and i am creating simple programs to start out but i ran into a problem with this:
My compiler says "M:\Java\DataType.java:22: integer number too large: 4000000002
k = 4000000002 ; // k to 4,000,000,002
^
1 error"
I Use JCreator.
and the Code is :
class datatype
{
public static void main(string args[])
{
double SQUARE_ROOT_OF_TWO = 1.414214;
int i; // i as an integer
long j; // j as a long integer
long k; // k as a long integer
float n; // n floating point number
long Speed_of_light;
long Speed_of_Sound;
long e;
Speed_of_light = (3.00e8);
e = Speed_of_light;
Speed_of_Sound = (340.292);
i = 3; // initialize i to 3;
j = -2048111; // j to -2,048,111

// The problem is This Line
k = 4000000002 ; // k to 4,000,000,002
//The problem is this line i cant see whats wrong with it.

n = (float) 1.887; // n to 1.887
System.out.println( SQUARE_ROOT_OF_TWO);
System.out.println( "i = " + i);
System.out.println( "j = " + j);
System.out.println( "k = " + k);
System.out.println( "n = " + n);
System.out.println(e);
System.out.println(Speed_of_Sound);
}
} // end of class DataType

You're using a signed long integer, which can only represent values from -2^31 to 2^31, use unsigned long to use numbers from 0 to 2^32-1.

I'm not trying to me a stickler, but for future reference, place your code in code tags. It makes it alot easier to read.

Thanks Guys and next time i will and i probably will =D

Edit:
I tried using the unsigned long but it gave me an error:

M:\Java\DataType.java:12: not a statement
unsigned long k; // k as a long integer
^
M:\Java\DataType.java:12: ';' expected
unsigned long k; // k as a long integer

different "number types" have limits http://java.sun.com/docs/books/tutor...datatypes.html

there is no unsigned in java

i think you were thinking about c++ since they are similar. or Visual Basic
and can anyone tell me whats wrong with the problem i have

You have to tell the compiler that 4000000002 is a long, rather than an integer. Sticking an L on the end does that:
