design ideas;
The random number is generated by using random, sequentially in the array, output random number addition calculation, in the form of a message box output.
Source code
Import javax.swing.*;
public class Sum {
public static void Main (String args[])
{
String output= "10 1000 or less random number: \ n";
int sum=0;
int a []=new int [10];
for (int i = 0;i<10;i++)
{
a[i]= (int) (Math.random () *1000);
Output + = "" +a[i];
Sum + = A[i];
}
Output + = "\ n 10 number of the and is:" +sum;
Joptionpane.showmessagedialog (Null,output, "results",
Joptionpane.plain_message);
}
}
;
Summary
Using random can randomly produce a number within 1-1000, add sum to complete the program.
