### Question:
EncodedValue { public long swap( long flags, EncodedValue otherEncoder ) { long otherValue = otherEncoder.getValue(flags); flags = otherEncoder.setValue(flags, getValue(flags)); return setValue(flags, otherValue); } EncodedValue( String name, int shift, int bits, double factor, long defaultValue, int maxValue );  EncodedValue( String name, int shift, int bits, double factor, long defaultValue, int maxValue, boolean allowZero ); long setValue( long flags, long value ); long getValue( long flags ); int getBits(); long setDefaultValue( long flags ); long getMaxValue(); long swap( long flags, EncodedValue otherEncoder );  }### Answer:
@Test public void testSwap() { EncodedValue instance1 = new EncodedValue("test1", 0, 10, 1, 5, 1000); EncodedValue instance2 = new EncodedValue("test2", 10, 10, 1, 5, 1000); long flags = instance2.setValue(instance1.setValue(0, 13), 874); long swappedFlags = instance1.setValue(instance2.setValue(0, 13), 874); assertEquals(swappedFlags, instance1.swap(flags, instance2)); }
