Add "JAVA" numbers

Design idea: define double variables I and s=0, define another variable n as a count, and then average it conveniently. In the program, the data is entered in I, through S to sum each data, and finally the average of N.

Program Flowchart:

SOURCE program code:

 PackageJiafa;ImportJava.util.*; Public classJia { Public Static voidMain (string[] args) {System.out.println ("Please enter the number of additions (Finally, enter any letter to end the input and perform the operation):"); Scanner Shuru=NewScanner (system.in); Doublei; DoubleS=0; intN=0;  while(Shuru.hasnextdouble ()) {i=shuru.nextdouble (); N++; S+=i; } System.out.println (The sum of the numbers of "+n+" is: "+s); System.out.print ("The average is:" +s/N); }}

Results:
