Method Details

write

public void write(int i)

Specified by:

write in class OutputStream

write

public final void write(byte[] b,
 int off,
 int len)

Overrides:

write in class OutputStream

capturedString

public String capturedString()

Returns:

the string that was written to System.out or System.err

capturedLines

public String[] capturedLines()

The capturedString(), divided on the line separator.

This includes leading, inner, and trailing empty lines but does not include the potential empty string that comes after a trailing line separator. (The exact algorithm is based on but behaves differently from String.split(String).)

Because the return value does not include a trailing empty line that comes from a trailing line separator, it can't be used to distinguish the cases where the last line was created by a print or a println. For more details and examples on this, see the documentation on standard input/output.

Returns:

the lines that were written to System.out or System.err
