The readBoolean() method of the ObjectInputStream class in Java reads a boolean from the stream.
Syntax:
public boolean readBoolean()
Parameters: This method does not accept any parameter.
Return Value: This method returns the boolean that has been read.
Errors and Exceptions: The function throws two exceptions which is described below:
- EOFException: The function is thrown if the end of file is reached.
- IOException: The function is thrown if an I/O error has occurred.
Below program illustrate the above method:
Program 1:
// Java program to illustrate // the above method import java.io.*;
public class GFG {
public static void main(String[] args)
{
try {
// create a new file
// with an ObjectOutputStream
FileOutputStream out
= new FileOutputStream( "gopal.txt" );
ObjectOutputStream out1
= new ObjectOutputStream(out);
// write
out1.writeUTF( "Geeks for Geeks" );
// Flushes the stream
out1.flush();
// create an ObjectInputStream
// for the file
ObjectInputStream example
= new ObjectInputStream(
new FileInputStream( "gopal.txt" ));
// Read from the stream
for ( int i = 0 ; i < example.available();) {
System.out.print( "" + ( char )example.read());
}
}
catch (Exception ex) {
ex.printStackTrace();
}
}
