Suppose that an instance of Account referenced by acc has been declared and initialised. See Unit 2 Section 6 for discussion of the class Account and its methods, which you will need to use to access the attributes of the accobject. Complete the provided code to initialise the result, by concatenating the number and balance of acc with appropriate text. For example if the account number was 0468 and the account balance was 2370.0 the result should evaluate to: Account number 0468 has a balance of 2370.0 Don't forget to include spaces where necessary and to end your statement with a semi-colon. Answer: (penalty regime: 10, 20, ... %) Reset answer 1 //Complete the statement to initialise the result string 2 |String result = Suppose that two instances of the class Account have been declared and initialised with non-zero balances. These objects are referenced by acc1 and acc2. An example expression to add the values of the two balances is given below: acc1. getBalance() + acc2.getBalance() In the box below, write an expression to calculate the balance of acc2 take away the balance of acc1 and to multiply the result by the balance of acc1 divided by 10 000. You should not attempt to round or otherwise format your answer. Remember that expressions do not end with a semi-colon. Answer: (penalty regime: 10, 20, ... %) Select the two correct statements below. This question is based on Unit 3 Section 2. Select one or more: In Java, in order to create a new instance of a class Thing and assign it to a reference variable of type Thing, we would write: new(); Thing t = '1' is an example of a literal value of the char primitive data type. A reference type variable can hold a reference to an object. Attributes of objects must be of reference types. Variable reference diagrams are used primarily to represent the state of an object. They only show the class of the object, its attributes (and their values) and its protocol. In Java the range of possible literal values for a particular primitive data type is unlimited
