### Question:
B2JsonReader { public boolean nextNonWhitespaceIsEof() throws IOException, B2JsonException { skipWhitespace(); return currentChar == EOF; } B2JsonReader(Reader in); char peekNextNotWhitespaceChar(); void skipValue(); String readNumberAsString(); String readString(); boolean startObjectAndCheckForContents(); boolean objectHasMoreFields(); boolean nextNonWhitespaceIsEof(); String readObjectFieldNameAndColon(); void skipObjectColon(); void finishObject(); boolean startArrayAndCheckForContents(); boolean arrayHasMoreValues(); void finishArray(); void readNull(); void readFalse(); void readTrue();  }### Answer:
@Test public void testNextNotWhitespaceIsEof() throws IOException, B2JsonException { { B2JsonReader reader = new B2JsonReader(new StringReader(" x ")); assertFalse(reader.nextNonWhitespaceIsEof()); } { B2JsonReader reader = new B2JsonReader(new StringReader(" \n assertTrue(reader.nextNonWhitespaceIsEof()); } }
