Solution 1:[1]

I would do something like this,or something similar:

I saw something similar in Stack Overflow: https://stackoverflow.com/a/15452462/8024829.

 double[][] array= {
   {1, 5},
   {13, 1.55},
   {12, 100.6},
   {12.1, .85} };

   java.util.Arrays.sort(array, new java.util.Comparator<double[]>() {
       public int compare(double[] a, double[] b) {
           return Double.compare(a[0], b[0]);
       }
   });

Solution 2:[2]

You can try this simple expression:

Arrays.sort(A, (a, b) -> a[0] - b[0]);
