Add array elements

Design ideas:

1. Generate random numbers in the array;

2. The final result is calculated by cyclic addition

3. Display results with Joptionpane.showmessagedialog

Flow chart:

SOURCE program code:

Import javax.swing.*;

public class Suijishu {

public static void Main (string[] args) {

TODO auto-generated Method Stub

Int[] arr=new int[10];// definition array

String output= "";

int j=0;

output+= "subscript\tvalue\n";

for (int i=0;i<10;i++)

{

arr[i]= (int) (Math.random () *100);// randomly generate integers in the 0-100 range

output+=i+ "\ t" +arr[i]+ "\ n";

}

JTextArea outputarea=new JTextArea (11,10);

Outputarea.settext (output);

for (int i=0;i<10;i++)

{

J+=arr[i];

}

Joptionpane.showmessagedialog (Null,outputarea, " array element ", joptionpane.information_message);

Joptionpane.showmessagedialog (Null,j, " array elements and ", joptionpane.information_message);

System.exit (0);

}

}

Operation Result:

Add array elements
