Number system program code to convert of Decimal numbers to Binary numbers in Java

class Dec2Bin

{

public static void main(String args[])

{

int decN=137, binN=0, i=1, j, tmp;

tmp=j=decN;

while(j>0)

{

binN=binN+(decN%2)*i;

decN/=2;

j/=2;

i*=10;

}

System.out.println("Decimal Number is: "+tmp);

System.out.println("Binary Number is:   "+binN);

}

}
