返回的位置可以通过indexOf()方法来获取,然后再使用substring()方法进行截取。 2. 示例代码 下面是一个简单的示例,演示如何在 Java 中截取指定字符前面的字符串: publicclassStringSplitter{publicstaticvoidmain(String[]args){Stringinput="Hello, this is a Java tutorial!";chardelimiter='i';Stringresult=getSu...
publicclassSubstringExample{publicstaticvoidmain(String[]args){Stringstr="Hello, this is a Java tutorial.";chardelimiter='i';// 查找分隔符位置intindex=str.indexOf(delimiter);// 如果找到分隔符则截取if(index!=-1){// 获取分隔符后面的字符串Stringresult=str.substring(index+1);System.out.println...
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 !!

In this quick tutorial, we’ll focus on the substring functionality of Strings in Java. We’ll mostly use the methods from theStringclass and few from Apache Commons’StringUtilsclass. In all of the following examples, we’re going to using this simple String: ...
varstr = "JavaScript Tutorial";varresult = str.substr(11); alert(result); Output : Tutorial slice()方法:这个方法有两个参数,起始和结尾,起始参数为必须,它决定了提取的起始位置.结尾参数不是必须的,它决定了终点的位置.终点位置的字母不会包含在提取出的substring里.如果终点参数缺省,那么从起始位置开始的...
