可变参数

  • JDK1.5 开始,java支持传递同类型的可变参数给一个方法。
  • 在方法声明中,在指定参数类型后加一个省略号(…)。
  • 一个方法只不过只能指定一个可变参数,它必须是方法的最后一个参数,任何普通的参数必须在它之前声明。
/** * 可变参数 */public class Variable {       public static void main(String[] args) {           printMax(1,2,3,4,5,69);    }    public static void printMax(int... number){           if (number.length==0){               System.out.println("没有数值比较");            return;        }        double result=number[0];        for (int i=1;i
result){ result=number[i]; } } System.out.println("最大值是:"+result); }}
