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: Stringtext="Julia Evans was bo...

Strings are immutable in Java, which means we cannot change aStringcharacter encoding. To achieve what we want,we need to copy the bytes of theStringand then create a new one with the desired encoding. First, we get theStringbytes, and then we create a new one using the retrieved bytes ...
It is recommended that anyone seeking this functionality use the split method of String or the java.util.regex package instead. 参考:https://docs.oracle.com/en/java/javase/15/docs/api/java.base/java/util/StringTokenizer.html StringTokenizer 原来是一个遗留类,并未被废弃,只是出于兼容性原因而被...

StringTokenizer is a legacy class that is retained for compatibility reasons although its use is discouraged in new code. It is recommended that anyone seeking this functionality use the split method of String or the java.util.regex package instead. The following example illustrates how the String...
