Integer massive

Question

Please help. Why answer is "true true"? How 053 can be equal 43 ? Thank you

public class Ex2 {
    public static void main(String[] args) {
        int a[] = { 1,2,053,4};
        int b[][] = { {1,2,4} , {2,2,1},{0,43,2}};
        System.out.print(a[3]==b[0][2] );
        System.out.print(" " + (a[2]==b[2][1]));
    }
}
