重写 toBinaryString() 方法：

public class Main {
    
    public static void main(String[] args) {
        int i1 = 0xaaaaaaaa;
        int i2 = 0x55555555;
        System.out.println("i1 = " + toBinaryString(i1));
        System.out.println("i2 = " + toBinaryString(i2));
        System.out.println("~i1 = " + toBinaryString(~i1));
        System.out.println("~i2 = " + toBinaryString(~i2));
        System.out.println("i1 & i2 = " + toBinaryString(i1 & i2));
        System.out.println("i1 | i2 = " + toBinaryString(i1 | i2));
        System.out.println("i1 ^ i2 = " + toBinaryString(i1 ^ i2));
        System.out.println("i1 & i1 = " + toBinaryString(i1 & i1));
        System.out.println("i1 | i1 = " + toBinaryString(i1 | i1));
        System.out.println("i1 ^ i1 = " + toBinaryString(i1 ^ i1));
        System.out.println("i2 & i2 = " + toBinaryString(i2 & i2));
        System.out.println("i2 | i2 = " + toBinaryString(i2 | i2));
        System.out.println("i2 ^ i2 = " + toBinaryString(i2 ^ i2));
    }

    private static String toBinaryString(int i) {
        StringBuilder sb = new StringBuilder();

        do {
            // 在开头插入
            sb.insert(0, ((i & 0x01) != 0) ? '1' : '0');
            i >>>= 1;
        } while (i != 0);
        return sb.toString();
    }
}
