ArrayList contains and equals

This is my Hole Class

class Hole { public int a; public int b; Hole[int a, int b] { this.a = a; this.b = b; }

So i adding an ArrayList that contain several several hole

public void checkPathLoop[int x, int y] { //rough code ArrayList leftFlowInnerHole = new ArrayList[]; //left holes rules leftFlowInnerHole.add[new Hole[0, 1]]; leftFlowInnerHole.add[new Hole[1, 5]]; leftFlowInnerHole.add[new Hole[5, 4]]; leftFlowInnerHole.add[new Hole[0, 4]];

when i add

Hole userInputHole = new Hole[0,1]; System.out.print[leftFlowInnerHole.contain[userInputHole]];

it always return false !! it suppose to return true.

Is there anything i miss ??

Thank you in advance
