Java中String字符串的截取

public static void main(String[] args) {
String str ="aaaaaaAbbbbbbAcccccc";
String[] ResultStr = str.split("A");
String aStr=ResultStr[0];
String bstr=ResultStr[1];
String cStr=ResultStr[2];
System.out.println(aStr);
System.out.println(bstr);
System.out.println(cStr);
//打印出来     aaaaaa
//       bbbbbb
//       cccccc

}
