Question

我有一个字符串

/*Here, C++ program constructor in struct*/ 
#include <iostream>
using namespace std;

struct hello
    {
    public:     //by default also it is public
        hello();    
        ~hello();
    };

hello::hello()
    {
    cout<<"calling constructor...!"<<endl;
    }

hello::~hello()
    {
    cout<<"calling destructor...!"<<endl;
    }

int main()
{
hello obj;      //creating a hello obj, calling hello constructor and destructor 

return 0;
}

我有一个arraylist

UITextField

现在我想使用这个arraylist从这个字符串中搜索。我怎么能不使用for循环呢？

Answer 1

使用Java 8流：

list.stream()
    .filter(s -> string.contains(s))
    .forEach(System.out::println);

Answer 2

您必须使用String.compare()功能逐一检查。这是你要问的吗？

Answer 3

for (String x : list) {
    if(string.contains(x)) {
        System.out.print(x);
    }
}

Answer 4

// Use JAVA 8 feature 
String str = "I would loved to be the part of cricket team";

ArrayList <String> list = new ArrayList(); 
list.add("part");
list.add("bend");
list.add("bet");
list.add("bear");
list.add("beat");
list.add("become"); 
list.add("begin");

boolean anyMatch = list.stream().anyMatch(s -> s.contains(str));
