### 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); String getName(); long getValue(long flags); int getBits(); double getFactor(); 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)); }
