Assignment #130: Making Arrays
Code
public class MakingArrays {
public static void main(String[] args) {
//Here we created an integer array with 5 elements
//int[] intArray = {4, 12, 15, 23, 100000};
//Here we created an integer array with 5 empty spots that can be filled with any integers
//int[] anotherIntArray = new int[5];
//Here is one way to initialize each of those empty spots
//anotherIntArray[0] = -11;
//anotherIntArray[1] = 0;
//anotherIntArray[2] = 211;
//anotherIntArray[3] = 17;
//anotherIntArray[4] = -1990;
//Here we created a String array with 3 elements
//String[] stringArray = {"Hello", ",", "world!"};
//Here we created a String array with 3 empty spots
//String[] anotherStringArray = new String[3];
//You can initialize each empty spot the same as before, only with strings here
//anotherStringArray[0] = "Mr.";
//anotherStringArray[1] = "Joshua";
//anotherStringArray[2] = "Davis";
//Using arrays in output is pretty much what you would expect
//System.out.println(intArray[0] + " + " + intArray[4] + " = " + (intArray[0] + intArray[4]));
//Sometimes things can be a bit weird
//Here the intArray[0] + intArray[4] are treated as strings
//System.out.println(intArray[0] + " + " + intArray[4] + " = " + intArray[0] + intArray[4]);
//Output with String arrays
//System.out.println(stringArray[0] + stringArray[1] + " " + stringArray[2]);
int[] intArrayPractice = {1, 2, 3};
System.out.println(intArrayPractice[0] + " " + intArrayPractice[1] + " " + intArrayPractice[2]);
String[] stringArrayPractice = new String[3];
stringArrayPractice[0] = "A ";
stringArrayPractice[1] = "string ";
stringArrayPractice[2] = "array.";
System.out.println(stringArrayPractice[0] + stringArrayPractice[1] + stringArrayPractice[2]);
