输入的数不是int,则导致getInputNumbers异常,从而导致add函数异常,则可以在add函数中抛出 一个链化的异常。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 publicstaticvoidmain(String[]args){System.out.println("请输入2个加数");int result;try{result=add();System.out.println("结果:"+result);}ca...
//给出一个String类型的数组,求其中所有不重复素数的和 public void distinctPrimarySum(String… numbers) { List<String> l = Arrays.asList(numbers); int sum = l.stream() .map(e -> new Integer(e)) .filter(e -> Primes.isPrime(e)) .distinct() .reduce(0, (x,y) -> x+y); // equi...

numbers.add(1); numbers.add(2); // Add all elements from primeNumbers to numbersnumbers.addAll(primeNumbers); System.out.println("Numbers: "+ numbers); } } Run Code Output Prime Numbers: [3, 5] Numbers: [1, 2, 3, 5] In the above example, we have created two arraylists namedpr...
That's all abouthow to create a function to add two numbers in Java. As you can see you have two approaches to create such function, first is you can create a method with two parameters and just return the addition of those two numbers or you can create a method using variable argument...
ArrayList<Integer> numbersList = new ArrayList<>(List.of(1, 2, 3, 4, 5)); ArrayList<Integer> evenNumList = numbersList.stream() .filter(n -> n % 2 == 0) .collect(Collectors.toCollection(ArrayList::new)); 5.4. 使用map()映射元素 ...
