把十进制转化了二进制

package binary;

public class BinaryTest {
    private int count;
    private int inputNumber;
    public BinaryTest() {
        Display display = new Display();
        this.inputNumber = display.get();
        String binaryNumber = Integer.toBinaryString(this.inputNumber);
        System.out.println(binaryNumber);
        char[] data = binaryNumber.toCharArray();
        for(int i = 0; i<data.length;i++){
            if(data[i] == '1')count++;
        }
        System.out.println(count);
    }
    public static void main(String[] args){
        new BinaryTest();
    }
}
