浅谈java 字符串,字符数组,list间的转化

String str =" aa.png,a2.png,a3.png";String[] arrayStr =new String[]{};arrayStr = str.split(",");

List list = java.util.Arrays.asList(arrayStr);

String[] storeStr = list.toArray(new String[list.size()]);

public class SplitTest {    public static void main(String args[]) {      String str = "a1.png,a2.png,a3.png";// 原始字符串     String[] arrayStr = new String[] {};// 字符数组     List<String> list = new ArrayList<String>();// list      arrayStr = str.split(",");// 字符串转字符数组     list = java.util.Arrays.asList(arrayStr);// 字符数组转list     String[] storeStr = list.toArray(new String[list.size()]);// list转成字符数组      /* 输出字符数组的值 */     for (String s : arrayStr) {       System.out.println(s);      }     System.out.println("-------------");     /* 输出list值 */     for (String s : list) {       System.out.println(s);      }     System.out.println("-------------");      for (String s : storeStr) {       System.out.println(s);      }     System.out.println("-------------");   } }
