Calculator Program - Use Strings And Methods To Include Arrays

Jul 23, 2014

My assignment is to essentially update a calculator program that uses strings, and methods, to include arrays. How to create and call an array that the user defines the size of and then inputs the numbers to fill the array. Here's the example my prof gave us of what the output should look like:

Menu
1. Add
2. Subtract
3. Multiply
4. Divide
5. Dot product
6. Generate random array
7. Quit

What would you like to do? 1

How many values are in the arrays? 3

Enter the values in the first array, separated by spaces:
2 4 6

Enter the values in the second array, separated by spaces:
1 3 5

The result is [3.0, 7.0, 11.0]

How to create an array that would allow the user to define the size of the array and then inputs the values for the array? I'm completely lost. I never should have taken java as an online class.

Arrays And Formatting Output - Data Integers

Jan 23, 2015

I am just learning arrays or rather teaching myself about them and I am not to sure how they work and why. I understand that in order to set one up you do

int[] example1;
example1 = new int[]{01, 02, 03, 04};

But I don't really understand is why if you only need 3 data integers, why put the 4th one in?

Also with outputting data, I understand .print() and .println() but I am not to sure what .printf() does and then the formatting after that.

System.out.printf("%3d%11") // and then what you want to print

After I enter the user int it just ends.

Static Method Related

Jan 31, 2014

Book says static methods can not access object instance variables. But the following code successfully prints out

ba.balance = 10
instance var = 5.

It seems like Static method is able to access the instance variable of another class, as well as the instance variable of main class. What gives ?

class InitProcess {
public static void main(String[] args) {
mymethod();
}
int x = 5;

How To Store 2 Related Elements Using 2x2 Array

Jul 16, 2014

I have the simple table below:

currency amount
€ 2.0
$ 4.0
£ 5.0

How could I store the currency and amount in an array? A 2x2 array would do this but how to store them and retrieve them is the challenge. For example, I have a method that asks the user for two inputs, the currency and the amount and using the array as a chat table where I could map the currency to the the currency input entered by the user, I could do some calculations with the amount entered by the user. how I could represent the 2x2 array?

Reading Only First Name From Strings?

Feb 12, 2014

I know that in c++ in order to read a string like

PHP Code:

. you need to use

getline(cin,string variable)

. In java, I have noticed that using

String name=keyboard.nextLine()

automatically reads the whole line...Suppose I wanted to read the first name only, how would I be able to accomplish that?

I need my code to print out the top three most common IP Addresses in the ArrayList. Right now I have it printing out the top IP Address. I am a little confused as to how to get it to print out three. Every time I change something, It doesn't give me the correct results

My Code:

private static ArrayList<String> ipAddress = new ArrayList<>();
private static String temp , mostCommon;
static int max = 0;

Pass By Value And Strings

Jul 19, 2014

Below is the snippet of code

public static void main(String[] args) throws Exception {
String s = "oldString";
reverse(s);
System.out.println(s); // oldString
}
public static void modifyString(String s) {
s = "newString";
System.out.println(s); // newString
}

I thought the first print statement would print "newString" as String is an object, and when we pass objects between methods, changing state of the object in any method reflects across the methods.

While Loops And Strings

Jan 3, 2014

So the while loop I am trying to use is:
while( type != "EXIT" ) {
type = input.next();
}

The problem is that typing in EXIT doesn't end the loop like I want it to. I also tried input.nextLine(); but neither of them work. The loop is being used to fill an ArrayList so the number of elements can change based on how many they want. What am I doing wrong, or what alternatives do I have?

Seems I need to use !type.equals("EXIT")

Java Won't Allow To Use Strings
