      Parameters:
      x - the object to print

    • println

      public void println(boolean x)
      prints the given boolean to the streams.
      Overrides:
      println in class PrintStream
      Parameters:
      x - the object to print

    • println

      public void println(String x)
      prints the given string to the streams.
      Overrides:
      println in class PrintStream
      Parameters:
      x - the object to print

    • println

      public void println(Object x)
      prints the given object to the streams (for Throwables we print the stack trace).
      Overrides:
      println in class PrintStream
      Parameters:
      x - the object to print

    • write

      public void write(int b)
      Writes the byte to the stream.
      Overrides:
      write in class PrintStream
      Parameters:
      b - the byte to write

    • write

      Writes the bytes to the stream.
      Overrides:
      write in class PrintStream
      Parameters:
      b - the bytes to write
      Throws:
      IOException

    • write

      public void write(byte[] buf, int off, int len)
      Writes the bytes to the stream.
      Overrides:
      write in class PrintStream
      Parameters:
      buf - the buffer to use
      off - the offset
      len - the number of bytes to write

    • append

      public PrintStream append(CharSequence csq, int start, int end)
      Appends a subsequence of the specified character sequence to this output stream.

      An invocation of this method of the form out.append(csq, start, end) when csq is not null, behaves in exactly the same way as the invocation 

      
     out.print(csq.subSequence(start, end).toString())
      Specified by:
      append in interface Appendable
      Overrides:
      append in class PrintStream
      Parameters:
      csq - The character sequence from which a subsequence will be appended. If csq is null, then characters will be appended as if csq contained the four characters "null".
      start - The index of the first character in the subsequence
      end - The index of the character following the last character in the subsequence
      Returns:
      This output stream
      Throws:
      IndexOutOfBoundsException - If start or end are negative, start is greater than end, or end is greater than csq.length()
      Since:
      1.5

    • append

      public PrintStream append(CharSequence csq)
      Appends the specified character sequence to this output stream.

      An invocation of this method of the form out.append(csq) behaves in exactly the same way as the invocation 

      
     out.print(csq.toString())

      Depending on the specification of toString for the character sequence csq, the entire sequence may not be appended. For instance, invoking then toString method of a character buffer will return a subsequence whose content depends upon the buffer's position and limit.

      Specified by:
      append in interface Appendable
      Overrides:
      append in class PrintStream
      Parameters:
      csq - The character sequence to append. If csq is null, then the four characters "null" are appended to this output stream.
      Returns:
      This output stream
      Since:
      1.5

    • append

      public PrintStream append(char c)
      Appends the specified character to this output stream.

      An invocation of this method of the form out.append(c) behaves in exactly the same way as the invocation 

      
     out.print(c)
      Specified by:
      append in interface Appendable
      Overrides:
      append in class PrintStream
      Parameters:
      c - The 16-bit character to append
      Returns:
      This output stream
      Since:
      1.5
