java code

here I create 2 classes
I asked the user to enter 2 numbers float or int dosnot matter (here how can I do 1 thing with 2 data type )
then find the max ,mini,+ , - , * , /
the problem is in calling the methods to the main

Write a program that creates an array of integers that stores the following values: 45,78, 12, 67, 55, 89, 23, 77, 88

Print only values that stored with even index including 0.

Do you mean this:


class Main {
  public static void main(String[] args) {
    OtherClass.someFunction();
  }
}

class OtherClass {
  // make sure it's static!
  static void someFunction() {
    
  }
}

Yes also this I have triple using [email protected]

Yeah, so just do that

can you join to see the problem in calling the function

(1083) OK BUT how can I call them in main
I want them out the main class

then put them in main

If you are talking about finding the min, max, and all those symbols for user input, try this code:


import java.util.Scanner; // Import the Scanner class

class MyClass {
  public static void main(String[] args) {
    int x, y, sum;
    Scanner myObj = new Scanner(System.in); // Create a Scanner object
    System.out.println("Type a number:");
    x = myObj.nextInt(); // Read user input

    System.out.println("Type another number:");
    y = myObj.nextInt(); // Read user input

    sum = x + y;  // Calculate the sum of x + y
    System.out.println("Sum is: " + sum); // Print the sum
  }
}

subtract


import java.util.Scanner; // Import the Scanner class

class MyClass {
  public static void main(String[] args) {
    int x, y, sum;
    Scanner myObj = new Scanner(System.in); // Create a Scanner object
    System.out.println("Type a number:");
    x = myObj.nextInt(); // Read user input

    System.out.println("Type another number:");
    y = myObj.nextInt(); // Read user input

    sum = x - y;  // Calculate the sum of x + y
    System.out.println("Sum is: " + sum); // Print the sum
  }
}

multiply


import java.util.Scanner; // Import the Scanner class

class MyClass {
  public static void main(String[] args) {
    int x, y, sum;
    Scanner myObj = new Scanner(System.in); // Create a Scanner object
    System.out.println("Type a number:");
    x = myObj.nextInt(); // Read user input

    System.out.println("Type another number:");
    y = myObj.nextInt(); // Read user input

    sum = x * y;  // Calculate the sum of x + y
    System.out.println("Sum is: " + sum); // Print the sum
  }
}

divide


import java.util.Scanner; // Import the Scanner class

class MyClass {
  public static void main(String[] args) {
    int x, y, sum;
    Scanner myObj = new Scanner(System.in); // Create a Scanner object
    System.out.println("Type a number:");
    x = myObj.nextInt(); // Read user input

    System.out.println("Type another number:");
    y = myObj.nextInt(); // Read user input

    sum = x / y;  // Calculate the sum of x + y
    System.out.println("Sum is: " + sum); // Print the sum
  }
}

Tell me if you need more.

also I want from the user to enter number and the user maybe enter integer or float

yeah, if you want that, you can just put a int, or float method around it.

How can you show me exactly [email protected]

wherever you see the nextInt() in my code i gave you. Just change it to whatever you want like float, and str.

I know this point but my teacher tell me that the user will enter a number (float , int ) I don’t know and my program should do the functions on these 2 number whatever they are

Do you advice me to make the numbers [email protected]

yes sure.
