[Introduction to programming in Java note] 1.3.7 converting to binary decimal to binary conversion

 Public classbinary{ Public Static voidMain (string[] args) {//Print binary representation of N.        intN = Integer.parseint (args[0]); intv = 1;  while(v <= N/2) v=v; //Now V is the largest power of 2 <= N.        intn = n;//Current Excess         while(V > 0)        { //Cast out the power of 2 in decreasing order.            if(N < v) {System.out.print (0); }            Else{System.out.print (1); n-=v;} V= V/2;    } System.out.println (); }}

Prints a binary representation of a 10-decimal number. Splits a number into the sum of a power of 2. For example 19 = 16 + 2 + 1. So the binary representation of 19 is 10011.
