定义一个一维数组，请把一维数组中索引为奇数的数组中赋值为从1到10之间的随机数，索引为偶数的数组中赋值为20到40之间的随机数！
我写的代码看哈那里需要修改:
import java.util.*;
public class shu {
public static void main(String[] args)
{
Random ran = new Random();
int[] x = new int[12];
ran.nextInt(x);
for(int i=0;i<=10;i+=2){
System.out.println("下标数为:"+i);
System.out.println("其随机数为:"+x[i]+" ");
}
ran.nextInt(x);
System.out.println("\n\n\n");
for(int i=1;i<=10;i+=2){
System.out.println("下标数为:"+i);
System.out.println("其随机数为:"+x[i]+" ");
}
}
}
