   Use a class:

    class TStar {
       long X, Y, Z;     // 3D location
       int Size;         // How big?
       int StarColor;
       TPoint Location;  // Screen location
    }

... and an array of references to it:

    TStar[] gStarField = new TStar[kNumOfStars+1];

   Let me raise a few stylistic points, though.  First,
the usual convention in Java is to use an initial upper-case
letter in the name of a class or interface, but to begin
names of methods and variables with lower-case letters:
TStar and TPoint above are fine, but most of the other names
ought to change.  Second, it might be a good idea to put
X,Y,Z (renamed x,y,z) into their own TPoint instance instead
of just letting them "float freely" in the TStar.  Third, the
name kNumOfStars is badly misleading, both in Pascal and in
Java; consider changing it.  Fourth, StarColor (starColor)
should probably be some kind of a Color object, possibly a
java.awt.Color, rather than a bare number.

class TStar
{
    long x, y, z;
    int size;
    int starColor;
    java.awt.Point location;
}

   static final int NUM_STARS = 100;

   TStar[] gStarArray = new TStar[NUM_STARS];
   for (int i = 0; i < NUM_STARS; i++)
      gStarArray[i] = new TStar();

As you obviously come from a procedural language, I assume that you
still have to grasp the general OO-concept (classes, objects, ...).
Hence you first need a good Java book or course with an OO-introduction,
too.
