print/draw Diamond Shape using Asterisk in java

public class Diamond
{
    public String Diamond_Asterisk(int num)
    {
        if(num>0)
        {
            return "*-" + Diamond_Asterisk(num-1);

        }
    }
     public String Diamond_Asterisk2(int num)
    {
        if(num>0)
        {
            return "-*-" + Diamond_Asterisk(num-1);
        }
        else
        {
            return "-";

    }

    public String Space(int num)

            System.out.print(Space(i));

        }
     
    }
    

}


//main class


import java.util.Scanner;

public class Main {

    public static void main(String[] args) 
    {
        Scanner input = new Scanner(System.in);

        System.out.print("Enter a number: ");
        int num = input.nextInt();

        Diamond access = new Diamond();
        System.out.println("The shape for this is: ");
        access.DiamondResult(num);
        
    }

}

===================================

Sample Output 1:
Enter a number: 3
The shape for this is:
---*--
--*-*--
-*-*-*--
--*-*--
---*--
Sample Output 2:
Enter a number: 4
The shape for this is:
----*--
---*-*--
--*-*-*--
-*-*-*-*--
--*-*-*--
---*-*--
----*--

Print Different Asterisk Shapes in java

//main method
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter a number: ");
int n = input.nextInt();
Asterisk1 access = new Asterisk1();
access.asterisk2(n);
}
}
//java class
public class Asterisk1 {
private int count = 0;
public void asterisk1(int n) {
if(n==0) {
System.out.println();
}
else {
System.out.print("*");
asterisk1(n-1); } }
public void asterisk2( int n) {
if(n==0){
return; }
else {
asterisk1(n);
asterisk2(n-1);
}
}
}

This program will output the asterisk in this form. If the number 4 is entered the form will be like this.
****

**
*
2. A Java source code for another Asterisk Form

/*The following code will have the same method as the first but different in implementation*/ //main method
public class Main {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter a number: ");
int n = input.nextInt();
Asterisk1 access = new Asterisk1();
access.asterisk2(n,1);
}
}
// java class
public class Asterisk1 {
private int count = 0;
public void asterisk1(int n) {
if(n==0) {
System.out.println();
}
else {
System.out.print("*");
asterisk1(n-1);
}
}
public void asterisk3(int count,int m) {
if( count == 0) {
System.out.println();
} else {
asterisk1(m);
asterisk3(n-1,m+1);
}
}
}

The output of this code if number 4 is entered will be like this.

**

To get a form that would look like this,

3. Here is the other code.

//main method
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter a number: ");
int n = input.nextInt();
Asterisk1 access = new Asterisk1();
access.asterisk2(n); access.asterisk3(n,1);
}
}
// java class
public class Asterisk1 {
private int count = 0;
public void asterisk1(int n) {
if(n==0) { System.out.println();
} else {
System.out.print("*");
asterisk1(n-1);
}
}
public void asterisk2( int n) {
if(n==0) {
return;
} else {
asterisk1(n);
asterisk2(n-1);
}
}
public void asterisk3( int n,int m)
{ if( n == 0) {
System.out.println();
} else {
asterisk1(m);
asterisk3(n-1,m+1);
}
}
}

4. Lastly, to acquire a shape like this,

here is the code:

//main method
package prog_proj2;
import java.util.Scanner;
public class Main {
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Enter a number: ");
int n = input.nextInt();
Asterisk1 access = new Asterisk1();
access.asterisk3(n); access.asterisk2(n);
}
}
//java class
public class Asterisk1 {
private int count = 0;
public static void asterisk1(int n) {
if(n==0) { System.out.println();
} else {
System.out.print("*");
asterisk1(n-1);
}
}
public void asterisk2( int n) {
if(n==0) { return;
} else {
asterisk1(n);
asterisk2(n-1);
}
}
public void asterisk3( int n) {
count++;
if( n == 0) {
return;
} else {
asterisk1(count);
asterisk3(n-1);
}
}
}

Java program to Read text File Line by Line

import java.io.*;

String strLine;
//Read File Line By Line
while ((strLine = br.readLine()) != null) {
// Print the content on the console
System.out.println (strLine);
}
//Close the input stream
in.close();
}catch (Exception e){//Catch exception if any
System.err.println("Error: " + e.getMessage());

}

Simple console print statement demonstration

  public void init ()
  {

    // Put code between this line
    //------------------------------------------
    double x = 5.0;
    double y = 3.0;
    System.out.println ("x * y = " + (x*y));
    System.out.println ("x / y = " + (x/y));

    // and this line.
    //------------------------------------------
  }

  // Paint message in Applet window.
  public void paint (java.awt.Graphics g) {
     g.drawString ("ConsolePrintApplet1",10,20);
  }
}

public class ConsolePrintApp1 extends java.applet.Applet
{
  public static void main (String [] args) {
    // Put code between this line
    //------------------------------------------

    double x = 5.0;
    double y = 3.0;
    System.out.println ("x * y = " + (x*y));
    System.out.println ("x / y = " + (x/y));

    //------------------------------------------
