this will help My entire code is posted below. My issue can be seen in this output: , When you do this
int numOfSymbols = keyboard.nextInt();
String userInputSymbol = keyboard.nextLine();
int numOfSymbols = keyboard.nextInt();
keyboard.nextLine(); // Throw away the '\n' from the line that contained int

How to loop user input in Java

will help you Use for loop and array that'll contain the data:
String[] inputs = new String[NUMBER_OF_INPUTS];
Scanner scanner = new Scanner();
for(i=0; i<NUMBER_OF_INPUTS; i++) {
   inputs[i] = scanner.nextLine();
}

My loop won't let me enter user input to end the loop :( (java)

This might help you try using input.nextLine(); after getting sides of the triangle, this will consume new line when you press enter.
try
public class Triangle
{
    public static void main (String[]args)

    {

        int x, y, z;
        String proceed="";
        do
        {
             Scanner input = new Scanner(System.in);
        System.out.println("Please enter the 3 sides of the triangle.");

        x = input.nextInt();
        y = input.nextInt();
        z = input.nextInt();
        boolean goAgain;
        String userInput;

        TriMethods triTest = new TriMethods(x, y, z);

        System.out.println("You entered a triangle with the sides " + triTest.toString() + ": ");

        triTest.isEqual();
        triTest.isIsos();
        triTest.isScal();
        input.nextLine();
        System.out.println("Would you like to go again? y/n");

        proceed = input.nextLine(); //THIS DOESN'T WORK

        }while (!proceed.equalsIgnoreCase("n"));
    }
}

Using the while loop to ask user their input in JAVA

around this issue Your current code is trying to use input for too many purposes: The current number entered, the amount of numbers of entered, and is also trying to use total as both the sum of all numbers entered and the amount of numbers to be entered.
You'll want 4 separate variables to track these 4 separate values: how many numbers the user will entered, how many they entered so far, the current number they entered, and the total.
int total = 0; // The sum of all the numbers
System.out.println("How Many Numbers You Want To Enter");
int count = kb.nextInt(); // The amount of numbers that will be entered
for(int entered = 0; entered < count; total++)
{
    int input = kb.nextInt(); // the current number inputted
    total += input; // add that number to the sum
}
System.out.println("Total: " + total); // print out the sum

Java loop- keeps on asking for user input

Hope that helps I looked at some other similar posts but was not able to figure out the solution, hence looking for your valuable input, thanks in advance. , You might use
 switch( ts.mySign() ){
 case '+':
     System.out.println ("You entered plus");
     break;
 case '-':
     System.out.println ("You entered mimus");
     break;
 case '*':
     System.out.println ("You entered asterisk");
     break;
 case '/':
     System.out.println ("You entered slash");
     break;
 default:
     System.out.println ("Input error");
     break;
}

I hope this helps . Below I am trying to sum the results of the user input. The program runs fine except that when it loops, the user inputs do not get added. Can you help point out what is incorrect? , Your problem is here:
System.out.println("Amount entered: " +coin);
