Java ObjectInputStream readChar() Method

The readChar() method of ObjectInputStream class is used to read a 16-bit (2 byte) char.

Syntax

Parameter

No parameter is passed.

Returns

The 16-bit char read.

Throws

EOFException - If the end of file is reached.

IOException - If other I/O error has occurred.

Example 1

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;

public class ObjectInputStreamreadCharsExample1  {
   public static void main(String[] args) throws IOException {
      
      byte[] buf = {'j', 'a', 'v', 'a', 'T', 'p', 'o', 'i', 'n', 't'};
      
      try {
         // create file output stream
       FileOutputStream   fileoutstream = new FileOutputStream("file1.txt");
         
         // create data output stream
        DataOutputStream dataoutstream = new DataOutputStream(fileoutstream);
         
         // for each byte in the buffer
         for (byte b:buf) {
            // write character to the dos
            dataoutstream.writeChar(b);
         }
         
         // force bytes to the underlying stream
         dataoutstream.flush();
         
         // create file input stream
         InputStream inpstream = new FileInputStream("file1.txt");
         
         // create new data input stream
        DataInputStream datainpstream = new DataInputStream(inpstream);
         
         // read till end of the stream
         while(datainpstream.available()>0) {
         
            // read character
            char c = datainpstream.readChar();
            
            // print
            System.out.print("    "+c);
         }
         
      } catch(Exception e) {
            
         e.printStackTrace();
      } 
   }
}

Output:

j    a    v    a    T    p    o    i    n    t

Example 2

import java.io.DataInputStream;
import java.io.DataOutputStream;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;

public class ObjectInputStreamreadCharsExample2  {
   public static void main(String[] args) throws IOException {
      
      byte[] carray = {'j', 'a', 'v', 'a', 'T', 'p', 'o', 'i', 'n', 't'};
      
      try {
         // create file output stream
       FileOutputStream   fileoutstream = new FileOutputStream("file1.txt");
         
         // create data output stream
        DataOutputStream dataoutstream = new DataOutputStream(fileoutstream);
         
         // for each byte in the buffer
         for (byte b:carray) {
            // write character to the dos
            dataoutstream.writeChar(b);
         }
         
         // force bytes to the underlying stream
         dataoutstream.flush();
         
         // create file input stream
         InputStream inpstream = new FileInputStream("file1.txt");
         
         // create new data input stream
        DataInputStream datainpstream = new DataInputStream(inpstream);
         
         // read till end of the stream
         for(int i=0;i<=carray.length;i++){ 
         
            // read character
            char c = datainpstream.readChar();
            
            // print
            System.out.print("    "+c);
         }
         
      } catch(Exception e) {
        
      } 
   }
}

Output:

j    a    v    a    T    p    o    i    n    t
