以下示例显示java.io.ObjectInputStream.readInt()方法的用法。
package com.jc2182;
import java.io.*;
public class ObjectInputStreamDemo {
public static void main(String[] args) {
int i = 319874;
try {
// create a new file with an ObjectOutputStream
FileOutputStream out = new FileOutputStream("test.txt");
ObjectOutputStream oout = new ObjectOutputStream(out);
// write something in the file
oout.writeInt(i);
oout.writeInt(1653984);
oout.flush();
// create an ObjectInputStream for the file we created before
ObjectInputStream ois = new ObjectInputStream(new FileInputStream("test.txt"));
// read and print an int
System.out.println("" + ois.readInt());
// read and print an int
System.out.println("" + ois.readInt());
} catch (Exception ex) {
ex.printStackTrace();
}
}
}
让我们编译并运行以上程序,这将产生以下结果-
