This approach, known as the common value method, proves to be a simple and readable technique for achieving uniform initialization in Java. By employing the common value method, we achieve a simple and effective way of initializing multiple variables with the same value. The output of the provid...
Directly using thefor-loopto merge the arrays isthe most efficient in terms of performance. It does not create unnecessary temporary variables and objects. We create a new array of combined length of two given arrays and then start putting items from both arrays into the new array in a loop...
