libgdx - Java Map with multiple primitive keys -

i'm looking have map in java/libgdx can take multiple primitive values key. concrete case have multiple position (x,y,z) need object attached.

at moment using (object)map list key, isn't there improve way?

the short reply question no, because primitive types can't java map keys. longer reply question easily, create position class -

static class position { int x; int y; int z; position(int x, int y, int z) { this.x = x; this.y = y; this.z = z; } public boolean equals(object b) { if (b instanceof position) { position other = (position) b; homecoming this.x == other.x && this.y == other.y && this.z == other.z; } homecoming false; } public int hashcode() { homecoming (integer.valueof(x).hashcode() ^ integer.valueof(y) .hashcode()) & integer.valueof(z).hashcode(); } }

then

map<position, object> map;

java libgdx
