java字符串转字符串列表

**We have to read total number string i.e. "n", create a list of the Strings and input "n" strings, add then to print the all stings of the list in Java.**

**我们必须读取总数字符串，即“ n”，创建字符串列表并输入“ n”字符串，然后添加以在Java中打印列表的所有字符串。**

**Declare a list of String implemented by ArrayList:**

**声明由ArrayList实现的String列表：**

List<String> str_list = new ArrayList<String>();

To input the total number of strings and to input string from the user, we are using in which is an object of scanner class.

到串并从用户输入字符串的总数，我们使用其中输入是扫描器类的对象。

The statement to read string and add to the list in the loop is:

读取字符串并添加到循环列表中的语句是：

str_list.add(in.next());

**Program:**

**程序：**

import java.util.*;
    
    public class ListExample {
        
    	public static void main (String[] args) {
        
    		//creating a list of integers
    		List<String> str_list = new ArrayList<String>();
    		int n;
    		Scanner in = new Scanner (System.in);
    		System.out.print ("Enter total number of strings: ");
    		n = in.nextInt ();
    
    		for (int i=0; i<n; i++){
        
    			System.out.print ("Enter name "+(i+1) +": ");
    			str_list.add(in.next ()) ;
    		}
    
    		//printing updated List
    		System.out.println ("string list: " + str_list);
    		//printing elements
    		System.out.println ("List elements: ");
    		for(String str: str_list){
        
    			System.out.println (str); 
    		}
    	}
    };

**Output**

**输出量**

Enter total number of strings: 5
    Enter name 1: Delhi
    Enter name 2: Noida
    Enter name 3: Mumbai
    Enter name 4: Gwalior
    Enter name 5: Bhind
    string list: [Delhi, Noida, Mumbai, Gwalior, Bhind]
    List elements:
    Delhi
    Noida
    Mumbai
    Gwalior
    Bhind
