About "Bit Pattern"

[Charles Cheng]

Hello~
I am a freshman in javaranch
thank teacher Yang brings me here.

the following is my question..

how to print out the bit pattern of a value in any kind of data type?
like byte,short,int,long,float,duoble etc.

int a=7;
print out "a":
00000000 00000000 00000000 00000111

you are so nice to answer this question...

Hello Charles, and welcome to the ranch.

class test {
public static void main(String[] args) {
int x = 2;

System.out.println(Integer.toBinaryString(x));
}
}

Hope this helps.

Welcome to JavaRanch, Charles!
Vicken's suggestion will be useful when working with the smaller integral primitive data types. Take a look at a very similar method in the Long class for working with that larger integral type. Also, take a look at the Double class documentation for a method that will help out with those floating point types.
