Question

java编程中总是运行出错，求各位高手帮个忙！

public class aa
{
public static void main(String args[])
{
int num1=12,num2=3,num3=25;
System.out.println("其中最大数是："+ Math.max(num1,num2,num3));
System.out.println("其中最小数是："+ Math.min(num1,num2,num3));
}
}

Answer 1

max应该只有2个参数吧

Answer 2

/**

final public class MaxDemo {
    /**
     * 求参数数组里最大值（需要JDK1.5以上版本来编译此源代码文件）
     * @param i
     * @return
     */
    static int getMax(int... i){
        int j=i[0];
        for (int a = 0, k = i.length-1; a < k; a++){
            j=Math.max(j,i[a+1]);
        }
        return j;
    }
    public static void main(String... args) {
        System.out.println(getMax(new int[]{-9,14,5,22,6,7}));
        System.out.println(getMax(new int[]{-9}));
    }
}
