源碼：
package reborn;
class Mug {
? Mug(int marker) {
? ? System.out.println("Mug(" + marker + ")");
? }
? void f(int marker) {
? ? System.out.println("f(" + marker + ")");
? }
}
public class hello {
? Mug c1;
? Mug c2;
? {
? ? c1 = new Mug(1);
? ? c2 = new Mug(2);
? ? System.out.println("c1 & c2 initialized");
? }
? hello() {
? ? System.out.println("Mugs()");
? }
? public static void main(String[] args) {
? ? System.out.println("Inside main()");
? ? hello x = new hello();
? }
}
輸出：
Inside main()
Mug(1)//先進行非靜態(tài)實例初始化
Mug(2)
c1 & c2 initialized
Mugs()
