DataOutputStream writeChar(int) in Java

writeChar(int): This method is available in the java.io.DataOutputStream class of Java.

Syntax:

Throws: IOException - if an I/O error occurs.

Approach

Java

import java.io.DataOutputStream;
import java.io.FileOutputStream;
import java.io.IOException;

public class DataOutputStreamwriteChar {
    public static void main(String[] args) throws IOException {

        FileOutputStream file = 
              new FileOutputStream("D:\\hello.txt");
        DataOutputStream data = new DataOutputStream(file);

        int v = 'A';
        data.writeChar(v);
        System.out.println("Successfully writes");
        data.close();

    }
}

Output:
