源程序代码：

// RandomInt.java

// Shifted, scaled random integers

import javax.swing.JOptionPane;

public class RandomInt {

public static void main( String args[] )

{

int value;

String output = "";

for ( int i = 1; i <= 1000; i++ ) {

value = 1 + (int) ( Math.random() * 6);

output += value + " ";

if ( i % 5 == 0 )

output += "\n";

}

JOptionPane.showMessageDialog( null, output,

"1000 Random Numbers from 1 to 6",

JOptionPane.INFORMATION_MESSAGE );

System.exit( 0 );

}

}

程序结果截图：

输出后换行，比如：System.out.println("a");System.out.println("b");结果：ab
