Overrides java.io.PrintStream.append.

Implements java.lang.Appendable.append.

Doc from java.io.PrintStream.append.

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.

Parameters

csq:CharSequence

The character sequence to append. If csq is null, then the four characters "null" are appended to this output stream.

Returns:PrintStream

This output stream

Annotations

@Override

Overrides java.io.PrintStream.append.

Implements java.lang.Appendable.append.

Doc from java.io.PrintStream.append.

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())

Parameters

csq:CharSequence

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:int

The index of the first character in the subsequence

end:int

The index of the character following the last character in the subsequence

Returns:PrintStream

This output stream
