how to get this to not consider 0, 1 and negative integers as prime. maybe using a "nested loop" or more than one loop?
//TestCode.java import java.util.Scanner; public class TestCode { public static void main(String[] args) { // Creating scanner object Scanner scan = new Scanner(System.in); boolean isPrime; int x; // Declaring an array with 10 ints int arr[] = new int[10]; // Reading values from user System.out.println("Enter 10 integer values for array:"); for(int i = 0;i<arr.length;i++){ arr[i] = scan.nextInt(); } // Looping through each value in array for(int i = 0;i<arr.length;i++){ x = arr[i]; // Assuming x is prime isPrime = true; // Loop through 2 to x-1 for(int j = 2;j<x;j++){ // if x is divisible by any of j if(x%j == 0) { // Then setting isPrime to false isPrime = false; } } // Printing value of x if it is a prime if(isPrime){ System.out.println(x); } } } }

This is in Python, I am trying to create a new window to print the data to screen, it prints fine in the terminal. I know this is a small segment of my code and its the only portion I am having a problem with. I was wondering if anyone can see what my problem may be. The current issue is
NameError: name 'fltVal' is not defined and AttributeError: 'PressureGUI' object has no attribute 'r_count'
Any help would be appreciated Based on the comment I made some changes which got me past the error above
The updated code is now with a new error of
File "/Volumes/NO NAME/CSE-222/Data Analysis

print_data_range_console
text= str(format(float,
'10.2f'))).grid(row=self.r_count,column=self.c_count)
TypeError: unsupported format string passed to type.__format__
I know it has to do with line 12 below but I am confused at this point
My output should be barometric pressue in the format of 1028.95 in one column and temp in the second column

CIT 149 JAVA 1 programming question.
The Assignment
This program will display a menu to the user from which they can
choose an option to find the area of a rectangle, the area of a
triangle, or to quit.
The user will make the selection and will be prompted to enter the
height and width, or the base and height, depending upon which
selection they made. The program will then calculate the
appropriate area and display the results.
This program will be in two classes, each in a separate file. One
will contain the main method and the other will contain instance
variables and methods which make up the program.
? Specifications
There are several ways in which this program could be written. However, in order to grade for following specifications and to have a clear path to a solution, it is required that you write your program using the specifications below.
The Instance Variables
Constructing the Methods
Create the following methods:
? All of the methods below will be in the class Area.
menu()
setFirstDimension() (Mutator)
setSecondDimension() (Mutator)
areaOfRectangle()
areaOfTriangle()
displayOutput()
