I am confused of what I am doing please help. Please in Java only. I don't know whot to do in C++

Task #2 writing the equals and toString methods 1. Write an equals method. The method compares the instance variables of the calling object with instance variables of the parameter object for equality and returns true if the dollars and the cents of the calling object are the same as the dollars and the cents of the parameter object. Otherwise, it returns false. 2. Write a toString method. This method will return a String that looks like currency, including the dollar sign. Remember that if you have less than 10 cents, you will need to put a O before printing the cents so that t appears correctly with 2 decimal places 3. Compile, debug, and test by running the MoneyDemo program. You should get the following output: The current amount is $500.00 Adding $10.02 gives $510.02 Subtracting $10.88 gives $499.14 $10.02 equals $10.02 $10.88 does not equal $10.02
