Question

Java程序中怎么获取cmd中输入的数字

Answer 1

2个办法
1）java Test.class 1 3 25
程序里面public static void main(String[] args) {
ags[0] = 1; ags[1] = 3; agrs[2] = 25

2) 利用Scanner来接受输入
java.util.Scanner scanner = new java.util.Scanner(System.in);
String input = scanner.next();
int value =scanner.nextInt();
String line = scanner.nextLine();
double dbValue =scanner.nextDouble();

Answer 2

再加个办法
class Test
{
public static void main(String[] args) throws Exception
{
Console cs=System.console();
if(null!=cs)
{
String str=cs.readLine();
double d=Double.parseDouble(str);
}
}
}
还有别的办法，如利用io包中的输入输出流来完成，只是呢有点麻烦啦
