Hello, In this blog we see the java code to print multiplication table. In this program user give the input and depends on that integer number the multiplication table will displayed.

Program:
import java.util.Scanner;
public class MultiTable1
{
    public static void main(String[] args)
    {
        Scanner s = new Scanner(System.in);
 System.out.print("Enter number:");       
 int n=s.nextInt();
        for(int i=1; i <= 10; i++)
        {
            System.out.println(n+" * "+i+" = "+n*i);
        }
    }
}

                  In the above code we use variable 's' to store the input value. And by using for loop the actual multiplication table is displayed.

Output:

Program:
1. (Using for loop)
public class Fibonacci
{
    public static void main(String[] args)
{
        int a = 0, b = 1;
        System.out.println("First 10 terms: ");
        for (int i = 1; i <= 10; ++i)
        {
            System.out.println(a + "  ");
            int sum = a + b;
            a = b;
            b = sum;
        }
    }
}


           In  the above program we use two variables that is a and b and assign the value 0 and 1 respectively. For loop is used to initialize the value of 'i' variable and increment it by 1. And we put the condition that is the 'i' must be less than or equal to 10. So we see the output of 10 numbers only.


2. Using while loop

public class Fibonacci
{
    public static void main(String[] args)
{
        int i = 1, a = 0, b = 1;
        System.out.println("First 10 terms: ");
        while(i<=10)
        {
            System.out.println(a + "  ");
            int sum = a + b;
            a = b;
            b = sum;
            i++;
        }
    }
}

In the above code instead of for loop we use the while loop and incremented I variable in the middle loop. The output of both code is exactly same.
   
Output:

Program:
class DisplayPattern
{
public static void main(String args[])
{
int i,j;
for(i=1;i<=5;i++)
{
for(j=i;j<=5;j++)
{
System.out.print("*");
}
System.out.println("");
}
}
}

Output:

                      Hello friends, In this blog, we see how to run the Java program. It is very simple to run the java program. To run the java code your machine must have a JDK (Java Development KIT) file. When you install it on your pc one folder named as Java is created in c drive. So, first of all, we see the simple java program to display "Hello I am Java Programmer". I will explain every stapes of the program.

Program:
class intro
{
public static void main(String args[])
{
System.out.println("Hello I am Java Programmer");
}
}
            To run the program there are two stapes in that First is Compilation and second is Interpretation.

Compilation: A compilation is one type of application softwere that translates or converts the code from human-readable code to machine-readable code i.e. in the form of 0 and 1. To make this conversion successful we must write a code on the notepad and save this code with extension .java. When we compile this code on command prompt, one same name file is created with extension .class and this file is in machine-readable form.
            To compile the java code the class name and file name must same. And to compile the code on command prompt type javac intro.java

Interpretation: Interpretation means the actual execution of the program, Once we successfully compile the program we can execute it easily. To run the java program on command prompt type java class_name i.e. java intro


Stapes to run the java program:
 Step 1: Go to that folder where your java code to be saved using the command prompt.
Step 2: Set the JDK path as shown below,
Note: In syntax, I wrote class_name which is the same as the file name.

Output:
