    int rows;
    rows=userInput.nextInt();
    for(int i=1; i<=rows; i++) {
      for(int j=1; j<=(2*rows-i); j++) {
        if(j>=i && (j+i)%2==0)System.out.print("* ");
        else System.out.print("  ");
      }

pattern

Main Logic :

for(int i=1; i<=rows; i++) {
  for(int j=1; j<=(2*rows-i); j++) {
    if(j>=i && (j+i)%2==0)System.out.print("* ");
    else System.out.print("  ");
  }
  System.out.print("\n");
}

You can print any thing in this pattern, just replace your value with *
