如何使用JAVA中的subString()截取字符串？如何操作呢？

Question

aaa bbb ccc ddd eee
怎么样用subString截取ccc ddd eee?

Answer 1

String a="aaa bbb ccc ddd eee ";String b=a.substring(0,3);String c=a.substring(4,7);String d=a.substring(8,11);String e=a.substring(12,15);String f=a.substring(16,19);System.out.println(b);System.out.println(c);System.out.println(d);System.out.println(e);System.out.println(f);——————————————————————————像这种有特定格式的可以用split更方便String a="aaa bbb ccc ddd eee ";String [] b=a.split(" ");for (int i = 0; i < b.length; i++) {System.out.println(b[i]);}已空格为分隔符截取出一个数组

Answer 2

String s="aaa bbb ccc ddd eee".substring(8,"aaa bbb ccc ddd eee".length())
