    This can be a concise way of solving it without code repetition.

    class Add {
     void add(int ...num){
        System.out.print(num[0]);
        print(Arrays.copyOfRange(num, 1, num.length));
        System.out.printf("=%d\n", IntStream.of(num).sum());
    }
    
    void print(int ...num){
        IntStream.of(num).forEach(i -> System.out.printf("+%d", i));
    }
    
}
