think, so I still look, deal with him.I heard that when bored to learn, because of learning, you will find there are more interesting things to interrupt you. 0-0 did not say study 0-0;int [] a B; what does this mean? Equivalent to an int a[],int b[] means declaring two variablesint [] a,b[]; What is this? 0-0 equivalent to int a[], int b[][]; This is a little bit more.Of course Java differs from C and C + +, and Java does not allow the number of elements in the array to be specified within the

The most recent data analysis requires a discrete value.My personal understanding is that the average of the difference between each number and the average of all numbersThe implementation method is as follows:public static double docal (double [] datas) {//mean double Pingjun = 0;//sum/number of double total = 0;for (int i =0;iThe Java implementation of discrete value calculation method

The main topic: given some alloys, choose the least alloy, so that these alloys can be synthesized according to the requirements of the alloyFirst of all, the idea of this problem is particularly fascinating to see how this problem can be thought of computational geometry and computational geometry and how to hang with Floyd.First of all because of a+b+c=1 so we just got a and B c=1-a-b so C can not read into theAnd then we abstracted each ingredient into a single point, and we know that the two

System.nanotime () method , this is more powerful, directly is the nanosecond-level timing method, than the above method of the accuracy of the 10^6 times, so for the time accuracy requirements are more comfortable with this method.UsageSuppose we need to test the time of the main () program:Method 1:Long start = calendar.getinstance ().
