This is my code please help!

package pattern;

public class Xpattern {

public static void main(String[]args) {
       for(int i=1;i<5;i++){
           for(int j=1;j<5;j++){
               if (i==j||i+j==5-1){
                   System.out.print(" * ");
               }
               else{

what pattern do you want. Its printing something if you send System.out.println() in previous block. something like this.

 *   *  
  *   
 *   *  
    *

for code:

public static void main (String[] args) throws java.lang.Exception
    {
           for(int i=1;i<5;i++){
            for(int j=1;j<5;j++){
               if (i==j||i+j==5-1){
                   System.out.print(" * ");
               }
               else{
                   System.out.print(" ");
               }
           }System.out.println();
       }
    }

try something like this.

see the comments inside the code for explanation:

    public static void main (String[] args) throws java.lang.Exception
    {
        // printing x shape;
        //print v and inverted v(outline of a pyramid)that is '\' and '/'
        int n=5;
                //printing V
        for (int i=1; i<n; i++)
        {
                        //printing '\ '
            for (int j=n-i; j<n-1; j++)
            {
                System.out.print(" ");
            }
            System.out.print("*");
            for (int j=i; j<n-1; j++)
            {
                System.out.print(" ");
            }

                        //printing '/'
            for (int j=i; j<n-1; j++)
            {
                System.out.print(" ");
            }
            System.out.println("*");

        }
                //printing inverted v
        for (int i=1; i<n; i++)
        {
            for (int j=i; j<n-1; j++)
            {
                System.out.print(" ");
            }
            System.out.print("*");
            for (int j=1; j<i; j++)
            {
                System.out.print(" ");
            }

        for (int j=1; j<i; j++)
            {
                System.out.print(" ");
            }

            System.out.println("*");

        }

    }
