Java Code Snippet: Redirect System.out into a string

Januar 19th, 2010 | By Christoph in Software-Development | No Comments »

For a simple test application / prototype I just wanted to just dump everything from System.out into a String, which I can output somewhere e.g. in a JSP file so that I see what’s going on. And yes, I didn’t want to setup a Logging framework for this…I want a String. Here it is:


OutputStream out = new ByteArrayOutputStream();
System.setOut(new PrintStream(out));
System.out.println(“Test”);
String sysout_content = out.toString();
System.out.println();
}

public static void main(String[] args) {

OutputStream out = new ByteArrayOutputStream();

System.setOut(new PrintStream(out));

System.out.println(“Test”);

String sysout_content = out.toString();

System.out.println();

}
