Learn tocompare two ArrayListin Java to find if they contain equal elements. If both lists are unequal, we will find thedifference between the lists. We will also learn to find common as well as different items
We can usecompareTo(Byte anotherByte)to compare two Byte objects numerically. The following table lists the return value fromcompareTo(Byte anotherByte). Let's give it a try. publicclassMain {publicstaticvoidmain(String[] args) {//fromjava2s.comByte byte1 =newByte("1"); Byte byte2 =ne...
