Java StringReader类是一个以字符串为源的字符流。它接受输入字符串并将其更改为字符流。它继承了Reader类。
在StringReader类中，未使用系统资源(如网络套接字和文件)，因此不需要关闭StringReader。
让我们看一下Java.io.StringReader类的声明：
public class StringReader extends Reader
| Method | Description |
|---|---|
| int read() | It is used to read a single character. |
| int read(char[] cbuf, int off, int len) | It is used to read a character into a portion of an array. |
| boolean ready() | It is used to tell whether the stream is ready to be read. |
| boolean markSupported() | It is used to tell whether the stream support mark() operation. |
| long skip(long ns) | It is used to skip the specified number of character in a stream |
| void mark(int readAheadLimit) | It is used to mark the mark the present position in a stream. |
| void reset() | It is used to reset the stream. |
| void close() | It is used to close the stream. |
import java.io.StringReader;
public class StringReaderExample {
public static void main(String[] args) throws Exception {
String srg = "Hello Java!! \nWelcome to Javatpoint.";
StringReader reader = new StringReader(srg);
int k=0;
while((k=reader.read())!=-1){
System.out.print((char)k);
}
}
}
输出：
Hello Java!!
Welcome to Javatpoint.
