Java generates binary addition problem

Counting daily is good for physical and mental health.

　　　　 int count = 50;
        Random random = new Random();
        for(int i = 0; i < count;i++) {
            int add = Math.abs(random.nextInt()) % 100;
            int added = Math.abs(random.nextInt()) % 100;
            int sum = add + added;
            
            System.out.println((i + 1) + "\t" + 
                    Integer.toBinaryString(add) + " + " + 
                    Integer.toBinaryString(added) + " = " + 
                    "\t\t答案：" + add + "+" + added + "=" + sum);
            
        }
