java(小练习)当读⼊的n 分别为1，2，3，4，5 时，输出的结果分别是什么

package com.fy.t2;

import java.io.*; 
import java.sql.*; 

class Test2{     
	public static void main(String args[]){       
		System.out.println("main 1");       
		int n;       //读⼊n       
		ma(4);       
		System.out.println("main2");  
		   
		}     
	public static void ma(int n){         
		try{           
			System.out.println("ma1");             
			mb(n);             
			System.out.println("ma2");   
			      
			}catch(EOFException e){           
				System.out.println("Catch EOFException");         
			}catch(IOException e){           
				System.out.println("Catch IOException");        
			}catch(SQLException e){           
				System.out.println("Catch SQLException");         
			}catch(Exception e){          
				System.out.println("Catch Exception");         
			}finally{           
				System.out.println("In finally");         
				}     
		}     
	public static void mb(int n) throws Exception{         
		if (n == 1) throw new EOFException();         
		if (n == 2) throw new FileNotFoundException();         
		if (n == 3) throw new SQLException();         
		if (n == 4) throw new NullPointerException();         
		System.out.println("mb2");     
		} 
	}

当n为4时的输出结果
