在Java中,我们可以使用substring()方法来截取字符串的一部分。该方法接受两个参数,分别是起始索引(inclusive)和结束索引(exclusive)。截取的结果将包含起始索引对应的字符,但不包含结束索引对应的字符。 下面是substring()方法的语法: Stringsubstring(intstartIndex,intendIndex) 1. 其中,startIndex表示要截取的起始位置,...

substring实现原理 String是Java中⼀个⽐较基础的类,每⼀个开发⼈员都会经常接触到。⽽且,String也是⾯试中经常会考的知识点。String有很多⽅法,有些⽅法⽐较常⽤,有些⽅法不太常⽤。今天要介绍的subString就是⼀个⽐较常⽤的⽅法,⽽且围绕subString也有很多⾯试题。substring(int...
In this short Java tutorial, we learned to get the substring of a specified string using the begin and end indices. We learned the rules about valid index values, and begin index is inclusive and end index is exclusive. Happy Learning !!
Note :Startindex is inclusive and endIndex is exclusive. Example publicclassSubstringExample2{ publicstaticvoidmain(Stringargs[]){ Stringstr="javainsimpleway"; System.out.println(str.substring(6,13)); } } Output simplew We can see that thesubstringreturned, has characters fromspecified starting ...
