What is the output of the following lines? System.out.println(values[2]); x values1] 2 values[4]; System.out.println(x); x-++values[3]; System.out.println(x); 2. setDescription(String str) and setUnit(int num) are the mutor methods of class Inventoryltem void setDescription (String str) void setDescription (String str) str Description = str; The following statement creates an Inventoryltem array: Inventoryltem[ ] items new Inventoryltem[5]; Is it correct or not to execute the following statements? If it is not correct, write the correct one a. items[0]. setDescription("Hammer" b. items.setUnit(10); 3. Use the following int array int [] numbers 78, 29, 12, 56, 98, 44, 75, 99, 17, 25 Write the code to store these values of intArray to a file name numbers.txt with the following format. Numbers 0 78 Numbers 1 29 Numbers 2 12 Numbers 3 56 Numbers 4 98 Numbers 5 44 Numbers 6 75 Numbers 7 99 Numbers 8 17 Numbers 9 25 Remember to close the fileExplanation / Answer
1.
i. System.out.println(values[2]) prints third element of the array. Which is 6.
ii. x = values[1] + 2*values[4]; System.out.println(x); Prints 5+(2*71) which is 147.
iii. x = ++values[3]; System.out.println(x); ++values[3] is the pre-increments operation and value[3] holds 4 and it is incemented and printed which is 5.
2.
a. items[0].setDescription(“Hammer”); Is a valid statement; It sets the Description of the first element in items as Hammer.
b. items.setUnit(10); is not a valid Statement; items[0].setUnit(10); is a valid statement; since items is an array of inventory elements and the mutor method implies on inventory object.
