Java中String[]类型与ArrayList类型之间转换

1、List转为String[]
List list = new ArrayList();
String[] stringArray = new String[2]; 
list.toArray(stringArray); 
  
//String str[] = list.toArray(new String[]{}); 

2、String[]转为List
String[] stringArray = new String[2]; 
List list = java.util.Arrays.asList(stringArray);
