You need to use a for loop nested in another for loop. The syntax would look something like:

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