Java方法练习:
自方法:随机数生成:
代码部分:
package lianxi;import javax.swing.JOptionPane;
public class bo {
public static void main(String[] args) {
int value;
String output = ""; for ( int i = 1; i <= 20; i++ )
{
value = 1 + (int) ( Math.random() * 6 );
output += value + " ";
if ( i % 5 == 0 )
output += "\n";
}
JOptionPane.showMessageDialog( null, output,
"20 Random Numbers from 1 to 6",
JOptionPane.INFORMATION_MESSAGE ); System.exit( 0 );
}
运行结果:
}
