以下示例显示java.io.CharArrayReader.read()方法的用法。
package com.jc2182;
import java.io.CharArrayReader;
import java.io.IOException;
public class CharArrayReaderDemo {
public static void main(String[] args) { CharArrayReader car = null;
char[] ch = {'H', 'E', 'L', 'L', 'O'};
try {
// create new character array reader
car = new CharArrayReader(ch);
int value = 0;
// read till the end of the file
while((value = car.read())!=-1) {
char c = (char)value;
// print the character
System.out.print(c+" : ");
// print the integer
System.out.println(value);
}
} catch(IOException e) {
// if I/O error occurs
e.printStackTrace();
} finally {
// releases any system resources associated with the stream
if(car!=null)
car.close();
}
}
}
让我们编译并运行以上程序,这将产生以下结果-
H : 72
E : 69
L : 76
L : 76
O : 79
