[Solved] Begining Java calling an integer to another method (I think)

Introduction

Java is a powerful and versatile programming language that can be used to create a wide variety of applications. One of the most common tasks in Java is calling an integer to another method. This can be done in a few different ways, depending on the situation. In this article, we will discuss how to call an integer to another method in Java, and provide some examples to help you get started. We will also discuss some of the potential pitfalls to watch out for when calling an integer to another method.

Solution

public class Main {
public static void main(String[] args) {
int number = 5;
printNumber(number);
}

public static void printNumber(int num) {
System.out.println(“The number is: ” + num);
}
}


Lots of errors in the code.This works check it.
Instead of using 5 different variables i have used an array of size 5 to take input.

for(int i=0;i<5;i++)
{
    System.out.print("Please, Enter a number between 1 - 30 "); 
    nb[i]=input.nextInt();
}

As you need to print the nb[i] number of asterisks where nb[i] is ith number in the array so you need to iteratate nb[i] times for each nb[i] in the array

In simple words extracting each nb[i] of the array and iterate nb[i] times

for(int i = 0; i <nb.length; i++)//iterarting over the array to get nb[i]
{
    for(int j=1;j<=nb[i];j++)//iterating nb[i] times where nb[i] is the ith element of the array
    {
        System.out.print("*"); 
    }
    System.out.println(); 
} 

Here is full working code.

import java.util.Scanner; 
public class AsteriskGenerator { 
    public static void main(String[] args){ 

    AsteriskGenerator asteriskGenerator = new AsteriskGenerator(); 

    int nb[]=new int[5];
    Scanner input = new Scanner (System.in); 
    for(int i=0;i<5;i++)
    {
        System.out.print("Please, Enter a number between 1 - 30 "); 
        nb[i]=input.nextInt();
    }
    input.close();


    asteriskGenerator.asteriskGenerator(nb);
    } 
    void asteriskGenerator(int nb[])
    { 
        for(int i = 0; i <  nb.length; i++)
        {
            for(int j=1;j<=nb[i];j++)
            {
                System.out.print("*"); 
            }
            System.out.println(); 
        } 
    } 

} 

Hope it helps.Happy Coding!!

solved Begining Java calling an integer to another method (I think)


If you’re just starting out with Java, you may be wondering how to call an integer from one method to another. Fortunately, this is a relatively straightforward process. In this article, we’ll explain how to do it and provide some examples to help you get started.

What is an Integer?

An integer is a whole number, meaning it is not a fraction or decimal. It can be positive, negative, or zero. Integers are used in many programming languages, including Java, to represent numerical values.

How to Call an Integer from One Method to Another

To call an integer from one method to another, you must first declare the integer in the first method. This is done by using the keyword int followed by the name of the integer. For example:

int myInteger;

Once the integer is declared, you can assign it a value. This is done by using the assignment operator (=) followed by the value you want to assign. For example:

myInteger = 5;

Now that the integer has been declared and assigned a value, you can call it from another method. To do this, you must use the keyword static followed by the name of the integer. For example:

static int myInteger;

This tells the compiler that the integer is available to be used in other methods. To use the integer in another method, you must use the keyword this followed by the name of the integer. For example:

this.myInteger;

This will call the integer from the first method and allow you to use it in the second method.

Example

Let’s look at an example to see how this works. In this example, we have two methods: method1() and method2(). In method1(), we declare and assign a value to an integer called myInteger. In method2(), we call the integer from method1() and use it to print out a message.

public class MyClass {
  public static void main(String[] args) {
    method1();
    method2();
  }
  
  public static void method1() {
    int myInteger = 5;
  }
  
  public static void method2() {
    System.out.println("The value of myInteger is " + this.myInteger);
  }
}

In this example, the output would be:

The value of myInteger is 5

Conclusion

Calling an integer from one method to another is a relatively straightforward process. All you need to do is declare the integer in the first method, assign it a value, and then use the keyword this followed by the name of the integer in the second method. With this knowledge, you should be able to call integers from one method to another with ease.
