State whether the following statements are True or False. Write down the question number and the word True or False next to it. E.g. 2.21 True 2.1 A computer can understand the Java programming language. 2.2 Comments are printed on the screen when the program is executed. 2.3 A variable cannot be accessed outside its scope. 2.4 Methods are one of the major structuring mechanisms for Java programs. 2.5 An algorithm is a plan for solving a problem by following a sequence of instructions. 2.6 Parameters are a way of making subprograms more generally applicable and useful. 2.7 A variable of type String is like a box in memory into which you can place Strings. 2.8 The value of the expression ( x = x) is true. 2.9 A non-terminating program is always a mistake. 2.10 The == operator can be used to see if two strings have the same characters. 2.11 JAVA is more similar to C++ that it is to Pascal. 2.12 JAVA programs are described as portable because they will fit into a small, lightweight disk. 2.13 It is important to test and evaluate a computer program. 2.14 The quotient / and the modulus % operators both do the same operation: divide a number. 2.15 The + operator has greater precedence that the * operator. 2.16 JOptionPane is a class which has methods for doing input and output operations. 2.17 The value of the expression 12 + 14 is 26. 2.18 You can write any program using sequence, selection and repetition. 2.19 The while loop test has the same type as the if-else statement test. 2.20 Sentinel loop control is appropriate where it is known in advance how many times the loop should iterate.
