I don't understand why my loop isn't working. Can someone help, please?

Question

public class PolarMain {
     public static void main(String[] args) {
          Polar p1 = new Polar(45, 50, 10, 10);
          System.out.println(" X1 " +p1.x1 +" New X1 " + p1.newX(45, 50 , 10 , 10)
           + " Y1 " +p1.y1 +" New Y1 " + p1.newY(45, 50 , 10 , 10));
     Polar p2 = new p2();
     for (i = 1; i < 10; i++)
     p2 = new (47, 49, 7, 7)
     System.out.println(" X1 " +p1.x1 +" New X1 " + p1.newX(47, 49 , 7 , 7)
           + " Y1 " +p1.y1 +" New Y1 " + p1.newY(47, 49, 7 , 7));
     I get the error message "illegal start of type" on line 14 and "identifier expected" on line 18.
TIA.

public class PolarMain {
    public static void main(String[] args) {
        // this code below is all within the main method... no problem
        Polar p1 = new Polar(45, 50, 10, 10);
        System.out.println(" X1 " +p1.x1 +" New X1 " + p1.newX(45, 50 , 10 , 10)
         + " Y1 " +p1.y1 +" New Y1 " + p1.newY(45, 50 , 10 , 10));
    // all of the code below here is within NO method.  Big problem.
    Polar p2 = new p2(); // what is new p2()?  Do you have a class p2 or an object p2.
    for (i = 1; i < 10; i++)
    p2 = new (47, 49, 7, 7)   // this is way out in left field.  new .... what?  no class name
    System.out.println(" X1 " +p1.x1 +" New X1 " + p1.newX(47, 49 , 7 , 7)
         + " Y1 " +p1.y1 +" New Y1 " + p1.newY(47, 49, 7 , 7));
    }This all suggests to me that in order for you to progress, in order for you to be at a level where we can advise you, you must study and understand the fundamentals of java first. We could re-write this code for you to get it to work, but for what purpose? You need to go over the introductory tutorials asap.
Good luck!
