Which of the following changes should be made so that the class definition compiles without error and the methodraisePrice works as intended?

Replace line 14 with price += surcharge;.

The method findLongest does not work as intended. Which of the following best describes the value returned by a call to findLongest ?

It is the number of occurrences of the value target in nums.

The following code segment appears in a method in a class other than Something. Something s = new Something(); Something.increment(); Which of the following best describes the behavior of the code segment?

The code segment creates a Something object s. The class Something's static variable count is initially 0, then increased by 5, then increased by 1.

Consider the following two code segments. Code segment II is a revision of code segment I in which the loop header has been changed. Which of the following best explains how the output changes from code segment I to code segment II?

The code segments print the same values but in a different order, because code segment I iterates from 1 to 5 and code segment II iterates from 5 to 1.

numItems = newNum; } } Which of the following best identifies the reason the class does not compile?

The updateItems method is missing a return type.

false

The code does not work as intended. Assume that the variable randomNumber has been properly declared and initialized. Which of the following initializations forrandomNumber will demonstrate that the code segment will not work as intended?

randomNumber = 0.70;

Consider the following code segment, which traverses two integer arrays of equal length. If any element of arr1 is smaller than the corresponding (i.e., at the same index) element of minArray, the code segment should replace the element of minArray with the corresponding element of arr1. After the code segment executes, minArray should hold the smaller of the two elements originally found at the same indices in arr1 and minArray and arr1 should remain unchanged.

remove lines 5-8
