Exam 8: Arrays and the Arraylist Class

What will be the value of x[1] after the following code is executed? int[] x = {22,33,44}; ArrayProcess(x); … Public static void arrayProcess(int[] a) { For(int k = 0;k < 3;k++) { A[k] = a[k] + 5; } }

Given the following two-dimensional array declaration,which statement is true? int [][] numbers = new int [6] [9];

Objects in an array are accessed with subscripts,just like any other data type in an array.

You can use this ArrayList class method to insert an item at a specific location in an ArrayList.

When an array is passed to a method

What would be the results after the following code was executed? int[] x = {23,55,83,19}; Int[] y = {36,78,12,24}; For(int a = 0;a < x.length;a++) { X[a] = y[a]; Y[a] = x[a]; }

A ragged array is

The ArrayList class is in this package.

What will be returned from the following method? public static float[] getValue(int x)

Which of the following for loops is valid,given the following declaration? String[] names = {"abc","def","ghi","jkl"};

This ArrayList class method is used to insert an item into an ArrayList.

What would be the results of the following code? final int SIZE = 25; Int[] array1 = new int[SIZE]; … // Code that will put values in array1 Int value = 0; For (int a = 0;a < = array1.length;a++) { Value += array1[a]; }
