Java program converts string to InputStream

Comprehensive Java Examples

In this program, we will learn how to convert a string to an InputStream in Java.

To understand this example, you should be familiar with the followingJava ProgrammingTopic:

Example: Java program to convert String to InputStream

Example

import java.io.ByteArrayInputStream;
import java.io.InputStream;
import java.nio.charset.StandardCharsets;
public class Main {
　　public static void main(String args[]) {
　　　　//Create a string
　　　　String name = "w3codebox";
　　　　System.out.println("The string is: ")　+　name);
　　　　try {
　　　　　　InputStream stream = new ByteArrayInputStream(name.getBytes(StandardCharsets.UTF_)8));
　　　　　　System.out.println("InputStream: ")　+　stream);
　　　　　　//Return the number of available bytes
　　　　　　System.out.println("Available bytes start: ")　+　stream.available());
　　　　　　//Read from the stream stream3bytes
　　　　　　stream.read();
　　　　　　stream.read();
　　　　　　stream.read();
　　　　　　//read3bytes later
　　　　　　//Return the number of available bytes
　　　　　　System.out.println("Last available byte: ",　+　stream.available());
　　　　　　stream.close();
　　　　}
　　　　catch (Exception e) {
　　　　　　e.getStackTrace();
　　　　}
　　}
}

Output Result

The string is: w3codebox
InputStream: java.io.ByteArrayInputStream@5479e3f
Starting available byte:　5
Last available byte:　2

In the above example, we created a string named name. Here, we convert the string to an input stream named stream.

The getBytes() method converts a string to bytes. For more information, please visitJava String getBytes()
