Array of stuctures in java?

Question

I need an array of length 3600 to hold a structure like value. Something like this:
typedef struct rangetype {
    float svy_vert_angle;
    float svy_dist;
    bool svy_exists;
} range;
range rg[3600];
for (int i = 0; i < 3600; i++) {
    rg.svy_vert_angle = i;
rg[i].svy_dist = i;
rg[i].svy_exists = false;
I know this is "c" like code, but I am trying to figure out how to do this in java. Any ideas? Thanks.

Actually, since java uses references for all objects, creating an array basically creates 3600 references to an object of class RangeType. You need to create an object itself to store values otherwise you get a NulLPointerException.
public class RangeType {  
public float svyVertAngle;   
public float svyDist;   
public boolean svyExists;
RangeType[] rg = new RangeType[3600]; 
  for (int i=0; i<rg.length; ++i) {
   rg[i] = new RangeType();    // Need to create an object for reference.
   rg.svyVertAngle = i;
