Convert InputStream To String In Java

In my previous example, I have written a simple program to covert string object to InputStream. This tutorial does the reverse, converting inputstream into a string object. Lets look at the example.

[code lang=”java”]
package javabeat.net.core;

import java.io.BufferedReader;
import java.io.ByteArrayInputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;

public class InputStreamToSTringExample {
public static void main(String[] args) throws IOException {
InputStream in = new ByteArrayInputStream(
"This is sample string".getBytes());
String resultVal = getResult(in);
System.out.println(resultVal);
System.out.println("Input Stream To String is completed");
}

private static String getResult(InputStream is) {
BufferedReader bufferedReader = null;
StringBuilder strBuilder = new StringBuilder();
String line;
try {
bufferedReader = new BufferedReader(new InputStreamReader(is));
while ((line = bufferedReader.readLine()) != null) {
strBuilder.append(line);
}

} catch (IOException e) {
e.printStackTrace();
} finally {
if (bufferedReader != null) {
try {
bufferedReader.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
return strBuilder.toString();
}
}
