今天写代码突然想着用两个输入流有什么效果import java.util.Scanner;public class ScannerTest { public static void main(String[] args) { Scanner input1 = new Scanner(System.in); Scanner input2 = new Scanner

看到这样一段代码public class A { private void print() { System.out.println("A"); } public static void main(String[] args) { A a = new B(); a.print(); B b = new B();
