求JAVA读程序题答案~
三、读程序，写结果
15．class Parent
{ void printMe()
{System.out.println("parent!");} }
class Child extends Parent
{ void printMe()
{System.out.println("child!");}
 void printAll()
  {super.printMe();this.printMe(); printMe(); } }
public class Test_this
{ public static void main(String args[])
{ Child myC=new Child();
 myC.printAll(); }}

16．public class Example
{ public static void main(String args[ ]) 
  { int n=0,m=0,t=555;
  try{ m=Integer.parseInt("8888");
  t=9999; 
  }
  catch(NumberFormatException e)
  { System.out.println("发生异常:"+e.getMessage());
  e.printStackTrace();
  n=123;
  }
  System.out.println("n="+n+",m="+m+",t="+t);
}
}

17．public class MyThread 
{ public static void main(String args[])
  { Lefthand left=new Lefthand();
Righthand right=new Righthand();
left.start();right.start();}}
class Lefthand extends Thread
{ public void run()
  { int i; 
for(i=0;i<3;i++)
  { System.out.print("red");
  try
  { sleep(300);}
  catch(InterruptedException e){}
  }}}
class Righthand extends Thread
{ public void run()
  { int i;
  for(i=0;i<3;i++)
  { System.out.print("blue");
  try
  { sleep(300); }
  catch(InterruptedException e){}
  }}}
18．public class ContinueDemo
{public static void main(String[] args)
{ int i,j;
  for(i=0;i<3;i++)
  for(j=0;j<3;j++)
  { if(i==j) continue;
System.out.println("j="+j);}  
System.out.println("i="+i); } }


------解决方案--------------------
15 老子 儿子 儿子
16 n=0,m=8888,t=9999
18 j=1
j=2
j=0
j=2
j=0
j=1
i=3
