Rectangle Overlap

Rectangle Overlap
An axis-aligned rectangle is represented as a list [x1, y1, x2, y2], where (x1, y1) is the coordinate of its bottom-left corner, and (x2, y2) is the coordinate of its top-right corner. Its top and bottom edges are parallel to the X-axis, and its left and right edges are parallel to the Y-axis.
Two rectangles overlap if the area of their intersection is positive. To be clear, two rectangles that only touch at the corner or edges do not overlap.
Given two axis-aligned rectangles rec1 and rec2, return true if they overlap, otherwise return false.
Example 1:

Input: rec1 = [0,0,2,2], rec2 = [1,1,3,3]
Output: true
Example 2:

Input: rec1 = [0,0,1,1], rec2 = [1,0,2,1]
Output: false
Example 3:

Input: rec1 = [0,0,1,1], rec2 = [2,2,3,3]
Output: false

class Solution {
    public boolean isRectangleOverlap(int[] rec1, int[] rec2) {
        return(rec1[0]<rec2[2]&&rec2[0]<rec1[2]&&rec1[1]<rec2[3]&&rec2[1]<rec1[3]);
    }
