### Question:
BASE1Header extends BaseHeader { public void setHFormat(int hformat) { header[1] = (byte) hformat; } BASE1Header();  BASE1Header(String source, String destination);  BASE1Header(String source, String destination, int format);  BASE1Header(byte[] header); int getHLen(); void setHFormat(int hformat); int getFormat(); void setRtCtl(int i); void setFlags(int i); void setStatus(int i); void setBatchNumber(int i); void setFormat(int format); void setLen(int len); void setDestination(String dest); void setSource(String src); String getSource(); String getDestination(); void swapDirection(); boolean isRejected(); String getRejectCode(); String formatHeader(); static final int LENGTH; }### Answer:
@Test public void testSetHFormat() throws Throwable { BASE1Header bASE1Header = new BASE1Header(); bASE1Header.setHFormat(100); assertEquals(22, bASE1Header.header.length, "bASE1Header.header.length"); }
