Question

用Java输入一个十进制，转换成二进制并输出

Answer 1

import java.util.Scanner;

public class ReversedBinary {

public static void main(String[] args) {
int number;

Scanner in = new Scanner(System.in);

System.out.println("输入一个十进制数");
number = in.nextInt();

if (number < 0) {
System.out.println("Error: Not a positive integer");
} else {

System.out.print("Convert to binary is:");
printBinaryform(number);
}
}

private static void printBinaryform(int number) {
int remainder;

if (number <= 1) {
System.out.print(number);
return;
}

remainder = number %2;
printBinaryform(number >> 1);
System.out.print(remainder);
}
}
