      • append

        public java.io.PrintStream append​(java.lang.CharSequence csq,

                                  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 java.lang.Appendable
        Overrides:
        append in class java.io.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:
        java.lang.IndexOutOfBoundsException - If start or end are negative, start is greater than end, or end is greater than csq.length()
        Since:
        1.5

      • append

        public java.io.PrintStream append​(java.lang.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 java.lang.Appendable
        Overrides:
        append in class java.io.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 java.io.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 java.lang.Appendable
        Overrides:
        append in class java.io.PrintStream
        Parameters:
        c - The 16-bit character to append
        Returns:
        This output stream
        Since:
        1.5
