Day6 基本for语句

1、public 和 private ：private 是声明私有类，私有类自己的类可以使用，而 public 公共成员的访问不仅可以来自外部，也可以来自内部；

 1 public class ForStatement {
 2     public static void main(String args[]) {
 3         forStatementTest();
 4     }
 5 
 6     private static void forStatementTest () {
 7         int tempN = 10;
 8         System.out.println("1 add to " + tempN + " is " + addToN(tempN));
 9         tempN = 0;
10         System.out.println("1 add to " + tempN + " is " + addToN(tempN));
11 
12         int tmepStepLength = 1;
13         tempN = 10;
14         System.out.println("1 add to " + tempN + " with step length " + tmepStepLength + " is: " + addToNWithStepLength(tempN, tmepStepLength));
15         
16         tmepStepLength = 2;
17         System.out.println("1 add to " + tempN + " with step length " + tmepStepLength + " is: " + addToNWithStepLength(tempN, tmepStepLength));
18     }
19     public static int addToN(int paraN) {
20         int resultSum = 0;
21         for (int i = 1; i <= paraN; i++){
22             resultSum += i;
23         }
24         return resultSum;
25     }
26     public static int addToNWithStepLength(int paraN, int paraStepLength) {
27         int resultSum = 0;
28         for (int i = 1; i <= paraN; i +=paraStepLength){
29             resultSum += i;
30         }
31         return resultSum;
32     }
33 }
