java基础测试题
答案为 C。
public Test(){
x=35;
}
public Test(String s){}
为构造方法，构造方法规定是不需要用void之类的修饰，也没有返回值
public void Test(double f){
this.x=(int)f;
}，这个则是与类名同名的方法，但这样的做法不赞同。

JAVA基础测试题
1 跟java运行的机制有关，java先加载静态域，static int x=10; ，然后静态块static { x+=5;}，static { x/=3;}（虽然位置在后但先运行） ，然后静态方法static void main
所以x=10，x=15，x=5.
2 A因为int [ ] x = new int[25]，数组建立后，每个元素默认值为0；x[24]=0；x[25] 下标越界，x[0]=0；
3 switch(i)不接受long型，int或者枚举型可以。i=Integer.parseInt(args[0]);虽然这样每课时i还是long型的。
4 c，没什么好说的，就是这么规定的！
