The standard approach to solving this problem is to first take input in the code itself. The input for our given problem is an integer number. To find log in java, to make things simpler, the Math package in Java already has a built in method named log for this. If you need log for...
logic : Use double for loop control to input a two-dimensional array, and then accumulate ai to output. extension : In an n-order square matrix (or n-order determinant), the diagonal line of n elements in the diagonal direction from the upper left corner to the lower right corner is ca...
So far, we showed the skeleton of oursimple Java server, which sits in a loop callingServerSocket.accept(). This method gets woken up with aSocketobject each time a client makes a connection, and we now need to process that connection. In our example "calculation" server, whenever the se...
