System.out.println("Enter Number of rows you want.");
        Scanner br = new Scanner(System.in);
        int num = br.nextInt();
        for(int i=0;i<num;i++)
        {
            for(int j=0;j<i;j++)
                System.out.print(" ");
            for(int j=0;j<(2*(num-i)-1);j++)
                System.out.print("*");
            System.out.println();
        }

scanner seems too complex. pls let me know how to do it in the simplest form.

Scanner is a class that provides you with some functions such as getting the input from user.You can just use
"int num=Integer.ParseInt(args[0])",which gets the first input from the command line when you run your program.If you just dont want to get the input from the user,you can just simply put "num=any number"

Scanner is just to take the input from the user the no of lines required. If you want it to do in a simple way without scanner you can fix the no of lines such as 5.

int num = 5;//No of Lines
        for(int i=0;i<num;i++)
        {
            for(int j=0;j<i;j++)
                System.out.print(" "); 
            for(int j=0;j<(2*(num-i)-1);j++)
                System.out.print("*");
            System.out.println();
        }
