int indexOf(String str, int fromIndex): It returns the index within this string of the first occurrence of the specified substring, starting at the specified index. int indexOf(String str, int fromIndex):它从指定的索引开始,返回指定子字符串首次出现在此字符串中的索引。 Example: 例: public cla...
There are methods to split the string into an array or to create substrings. SinceString is immutable, the original string remains unchanged and a new instance of string is returned. 由于String是不可变的,因此原始字符串保持不变,并返回新的string实例。 (Java String Functions List) Here is the ...

Allocates a new String that contains characters from a subarray of the Unicode code point array argument. The offset argument is the index of the first code point of the subarray and the count argument specifies the length of the subarray. The contents of the subarray are converted to chars;...
一、String实现源码分析 1、String的定义 复制 publicfinal class String implements java.io.Serializable, Comparable, CharSequence 1. 从上,我们可以看出几个重点: String是一个final类,既不能被继承的类 String类实现了java.io.Serializable接口,可以实现序列化 ...
