A+B的心得

正确的代码段

import java.util.*;
public class Main  {

	public static void main(String[] args) {
         Scanner scanner =  new Scanner(System.in);
          while(scanner.hasNext()) {
        	 int number=scanner.nextInt();
        	 if(number==0) {
        		 break;
        	 }else {
        		 **int sum=0;**
        		 int a[]=new int [1024];
        		 for(int i=0;i<number;i++)
        		 { 
        			 a[i]=scanner.nextInt();
        			 sum=sum+a[i];
        		 }
        		 System.out.println(sum);
                
        	 }
        	
          }
        	  
          
         
		
		
	}

	
}

错误的代码段

import java.util.*;
public class Main  {

	public static void main(String[] args) {
	    **int sum=0;**
         Scanner scanner =  new Scanner(System.in);
          while(scanner.hasNext()) {
        	 int number=scanner.nextInt();
        	 if(number==0) {
        		 break;
        	 }else {
        		 
        		 int a[]=new int [number];
        		 for(int i=0;i<number;i++)
        		 { 
        			 a[i]=scanner.nextInt();
        			 sum=sum+a[i];
        		 }
        		 System.out.println(sum);
                
        	 }
        	
          }
        	  
          
         
		
		
	}
