第5天第7节： 新特性对数组的支持

After JDK1.5

==foreach for array
int y[]={1,3,5,};
for(int z:y)System.out.print(z+"\t");  ==>1 3 5

==varying number of args
    int y[]={1,3,5}
    fun(1,3,5,7);
    fun(1);
    fun(y);

    public static void fun(int ... arg) {
        for(int x:arg)System.out.print(x+"\t");
        System.out.println();
    }
