Java: Receives multiple numbers from the command line and outputs the result after summing

Design ideas: Get the number of inputs, and then convert the numbers to be added to float to add, and then output the results.

Flow chart:

1: Set up a scanner object scan;

2: Define a dynamic array adoublearray[];

3: Using the loop structure to input the number into the array;

4: Use the loop structure to add the numbers in the array to the output.

Source:

 PackageNiuke;ImportJava.util.Scanner; Public classAdd { Public Static voidMain (string[] args) {Scanner scan=NewScanner (system.in); intN; System.out.println ("Please enter a few numbers to sum"); N=scan.nextint ();//Enter the number of requirements and the number of      Double[] adoublearray; Adoublearray=New Double[n]; System.out.println ("Please enter" +n+ "number");  for(inti=0;i<adoublearray.length;i++) {Adoublearray[i]=scan.nextint ();//Enter a number of n sums      }//converts the input string to a floating-point type      DoubleResult=0;  for(inti=0;i<adoublearray.length;i++) {result+=Adoublearray[i]; }system.out.println ("The added result is" +result);//calculate and output results}}
