### **方法一：用 continue** ###

package java_1;
    
    import java.util.Scanner;
    
    public class Exercises_2{
    	public static void main(String[] args){
    		Scanner input=new Scanner (System.in);
    		try {
    			int a,i,score,first=0,second=0;
    			String first_1="",second_1="",name;
    			System.out.print("Please input how many students : ");
    			a=input.nextInt();
    			for(i=0;i<a;i++)
    			{
    				name=input.next();
    				score=input.nextInt();
    				if(score>first)  //如果新输入的成绩比最高成绩（first）还高
    				{
    					second=first;       //先把最高成绩赋给第二最高成绩
    					second_1=first_1;  
    					first=score;       //把新输入的成绩赋给最高成绩
    					first_1=first+" "+name;
    					continue;          //结束本次循环，继续下一次循环
    										
    				}
    				if(score>second)   //如果此成绩比最高成绩小，并且比第二最高成绩大
    				{
    					second=score;   //把新输入的成绩赋给第二最高成绩
    					second_1=second+" "+name;
    				}
    			}
    			System.out.println("The highest score and name is "+first_1);
    			System.out.println("The second heigh score and name is "+second_1);
    		}
    		finally {
    			input.close();
    		}
    	}
    }

###  **方法二：**加附条件 ###

package java_1;
    
    import java.util.Scanner;
    
    public class Exercises_2{
    	public static void main(String[] args){
    		Scanner input=new Scanner (System.in);
    		try {
    			int a,i,score,first=0,second=0;
    			String first_1="",second_1="",name;
    			System.out.print("Please input how many students : ");
    			a=input.nextInt();
    			for(i=0;i<a;i++)
    			{
    				name=input.next();
    				score=input.nextInt();
    				if(score>first)  //如果新输入的成绩比最高成绩（first）还高
    				{
    					second=first;       //先把最高成绩赋给第二最高成绩
    					second_1=first_1;  
    					first=score;       //把新输入的成绩赋给最高成绩
    					first_1=first+" "+name;
    					
    										
    				}
    				if(score>second&&score!=first)   //如果此成绩比第二最高成绩大，并且此成绩不等于最高成绩
    				{
    					second=score;   //把新输入的成绩赋给第二最高成绩
    					second_1=second+" "+name;
    				}
    			}
    			System.out.println("The highest score and name is "+first_1);
    			System.out.println("The second heigh score and name is "+second_1);
    		}
    		finally {
    			input.close();
    		}
    	}
    }
