Array class Assignments

Array class Assignments

First, design ideas

Define an array of length 10, then generate 10 1-10 random numbers, store them in an array, then display them in a dialog box, then define a sum function and output 10 numbers.

Second, the source program code

Package SDDW;

import javax.swing.*;

Public class SWW { public static void main (String args[]) {

int i;

double A;

String output= "";

Double []b=new double [10];

for (i=1;i<b.length;i++)

{

A=math. Random () *10;

B[i]=a;

}

Output + = "subscript\tvalue\n";

for (i = 0; i < b.length; i++)

Output + = i + "\ t" + b[i] + "\ n";

JTextArea Outputarea = new jtextarea (11, 10);

Outputarea.settext (output);

Joptionpane. Showmessagedialog ( null, Outputarea,

"Initializing an Array with a Declaration",

Joptionpane. information_message );

double sum=0;

for (i=0;i<b.length;i++)

{

Sum+=b[i];

}

Joptionpane. Showmessagedialog ( null, SUM,

"Initializing an Array with a Declaration",

Joptionpane. information_message );

}

}

Iii. Results
