java - For-loop gives only one value when iterating through an array of Vectors (libGDX) -

i'm beginner, here's small mistake can recognize yeah... i'm using libgdx library , here's code of method:

public vector2[] initcollisionstart() {      int = 0;      (int row = 0; row < currentmapheighttiles; row++) {         (int col = 0; col < 9; col++) {             if (currentmap[row][col] == 4) {                 i++;             } else if (currentmap[row][col] == 3) {                 i++;             }         }     }      gdx.app.log("initcollisionstart", "works");      vector2[] collisionstart = new vector2[i];      (int row = 0; row < currentmapheighttiles; row++) {         (int col = 0; col < 9; col++) {             if (currentmap[row][col] == 4) {                 position.x = col * 40;                 position.y = row * 40;                 collisionstart[i - 1] = position;                 system.out.println("collisionstart[" + + "] = " + collisionstart[i - 1]);                 i--;             } else if (currentmap[row][col] == 3) {                 position.x = col * 40;                 position.y = row * 40;                 collisionstart[i - 1] = position;                 system.out.println("collisionstart[" + + "] = " + collisionstart[i - 1]);                 i--;             }         }     }      collisioninitialized = true;     system.out.print("\n");     (int z = 0; z < collisionstart.length; z++) {         system.out.println("collisionstart[" + z + "] = " + collisionstart[z]);     }     return collisionstart; } 

and output looks that:

initcollisionstart: works collisionstart[7] = [40.0:5760.0] collisionstart[6] = [80.0:5760.0] collisionstart[5] = [120.0:5760.0] collisionstart[4] = [160.0:5760.0] collisionstart[3] = [200.0:5760.0] collisionstart[2] = [240.0:5760.0] collisionstart[1] = [280.0:5760.0]  collisionstart[0] = [280.0:5760.0] collisionstart[1] = [280.0:5760.0] collisionstart[2] = [280.0:5760.0] collisionstart[3] = [280.0:5760.0] collisionstart[4] = [280.0:5760.0] collisionstart[5] = [280.0:5760.0] collisionstart[6] = [280.0:5760.0] 

and here's question. why every value of collisionstart array equals [280.0:5760.0] when use outside of double for-loop? expect return same value initialized earlier. there way this?

thanks in advance <3

in second double loop

 collisionstart[i - 1] = position; 

should changed to

collisionstart[i - 1] = new vector2(...); 

i not sure getting position from.
assume vector2 assign every element of vector2 array.
entire array pointing same object, , hence output outside loop.
