Java : 配列のequals()メソッドがぐったりな件 - lethevert is a programmerたとえば、 public class Comp { public static void main(String[] args) { int[] a = new int[] { 1, 3, 8, }; int[] b = new int[] { 1, 3, 8, }; System.out.println(a == b); System.out.println(a.equals(b)); System.out.println(java.util.Arrays.equals(a, b)); } }なら、結果は false false trueこうすると public class Comp { public static void main(String[] args) { Object[] a = new Object[] { new int[] {1,2}, new int[] {3,4}
