java之try与finally语句（2）

接上一篇，跟上一篇代码差不多，就是修改了a的值为double类型。

 

public class TryTest 
{
	public static void main(String[] args)
	{
		TryTest tt = new TryTest();
		
		tt.test1();
		
		System.out.println();
		
		tt.test2();
		
		System.out.println();
		
		tt.test3();
	}
	
	public void test1()
	{
		double a = 2.0;
		
		System.out.println("start");
		
		try
		{
			a = a/0;
			
		}catch(Exception e)
		{
			System.out.println("catch");
			
		}finally
		{
			System.out.println("finally");
		}
		
		System.out.println("end");
	}
	
	public void test2()
	{
		double a = 2.0;
		
		System.out.println("start");
		
		try
		{
			a = a/0;
			
		}catch(Exception e)
		{
			System.out.println("catch");
			
			return;
			
		}finally
		{
			System.out.println("finally");
		}
		
		System.out.println("end");
	}
	
	public void test3()
	{
		double a = 2.0;
		
		System.out.println("start");
		
		try
		{
			a = a/0;
			
		}catch(Exception e)
		{
			System.out.println("catch");
			
			System.exit(0);
			
		}finally
		{
			System.out.println("finally");
		}
		
		System.out.println("end");
	}
}

 

输出为：

 

start
finally
end

start
finally
end

start
finally
end
