Approach 1: When no exception

Java

import java.io.StringWriter;
import java.io.Writer;

public class Writerwrite2 {
    public static void main(String[] args) throws IOException {

        Writer writer = new StringWriter();

        int c = 'a';

Java

package com.Writer;

import java.io.IOException;
import java.io.PipedWriter;
import java.io.Writer;

public class Writerwrite2 {
    public static void main(String[] args) throws IOException {

        Writer writer = new PipedWriter();

        int c = 'a';
        writer.write(c);

        System.out.println("Successfully writes");

        writer.close();
    }
}

Output:
