public class Test {
public static void main(String [] args){
ArrayList<Double> list=new ArrayList<Double>();
DecimalFormat sog = new DecimalFormat("###.##");
Random rand=new Random();
for(int i=0;i<20;i++){
double dd=rand.nextInt(100)+Double.valueOf(sog.format(rand.nextDouble()));
list.add(dd);
}
Double[] de=list.toArray(new Double[list.size()]);
System.out.println("打印20个数:");
for(int j=0;j<de.length;j++){
System.out.print(de[j]+" , ");
}
Collections.sort(list);
Double[] df=list.toArray(new Double[list.size()]);
System.out.println("\n从小到大排序打印20个数:");
for(int t=0;t<df.length;t++){
System.out.print(df[t]+" , ");
}
}
}
