How to increment a value by X

问题

  1. 我正在尝试找到一个适用于下面计算的 Java 代码，
  3. 找不到如何将值递增 53 和 79，
  5. 	
  6.  
  8. 	public static void main(String[] args) {
  10. 	    int weight, b;
  12. 	    Scanner sc = new Scanner(System.in);
  13. 	    System.out.print("输入重量：");
  14. 	    weight = (int) sc.nextDouble();
  15. 	    b = calculateLandingRate(weight);
  17. 	    System.out.println("总价格：" + b);
  18. 	}
  19. 	static int calculateLandingRate(int weight) {
  21. 	    int rate = 26;
  23. 	    if (weight <= 25) {
  24. 	        if (weight > 1) {
  25. 	            int totalPrice = 26 * weight;
  26. 	        } else if (weight > 25 && weight < 75) ;
  28. ------------------------------------------------------------
  30. 总价=（重量为26kg）+ 53，
  31. 计算应该是值从26kg开始递增53，
  33.             /* int rate = +53;
  34.             26kg时的总价 = 650 + 53 =703
  35.             27kg时的总价 = 703 + 53 =756
  36.             28kg时的总价 = 756 + 53 =809
  37.             29kg时的总价 = 809 + 53 =862
  38.             30kg时的总价 = 862 + 53 =915
  40.             *
  41.             *
  42.             *
  44.             75kg时的总价 = 3247 + 53 =3300
  45.        */
  46.     } 
  48.     else if (weight > 75) ;
  51.    值递增 79
  53.    int rate = +79;
  55.     76kg时的总价 = 3300 + 79 =3379
  56.     *
  57.     *
  58.     *
  59.     *
  61.     624 kg时的总价 = 46592 + 79 =46671

I'm trying to find a java code to my calculation below,

can't find how to increment the value by 53 and 79 ,

  1. public static void main(String[] args) {
  2. int weight, b;
  3. Scanner sc = new Scanner(System.in);
  4. System.out.print(&quot;Enter the Weight : &quot;);
  5. weight = (int) sc.nextDouble();
  6. b = calculateLandingRate(weight);
  7. System.out.println(&quot;Total price  : &quot; + b);
  8. }
  9. static int calculateLandingRate(int weight) {
  10. int rate = 26;
  11. if (weight&lt;= 25) {
  12. if (weight &gt; 1) {
  13. int totalPrice = 26 * weight;
  14. } else if (weight&gt; 25 &amp;&amp; weight &lt; 75) ;`

total price= (the weight 26kg ) + 53 ,
the calculation should be like the value is incremented by 53 ,from the weight =26kg

  1.        /* int rate = +53;
  2. Total price at 26kg = 650 + 53 =703
  3. Total price at 27kg = 703 + 53=756
  4. Total price at 28kg = 756 + 53 =809
  5. Total price at 29kg = 809 + 53 =862
  6. Total price at 30kg = 862 + 53 =915
  7. *
  8. *
  9. *
  10. Total price at 75kg = 3247 + 53 =3300
  11. */
  12. } 
  13. else if (weight &gt; 75) ;

the value increment by 79

int rate = +79;

  1. Total price at 76kg = 3300 + 79 =3379
  2. *
  3. *
  4. *
  5. *
  6. Total price at 624 kg = 46592 + 79 =46671

我认为你想要的是这样的：

  1. static int calculateLandingRate(int weight) {
  3.     int lowRate = 26;
  4.     int midRate = 53;
  5.     int highRate = 79;
  7.     int lowRateLimit = 25;
  8.     int midRateLimit = 75;
  10.     int totalPrice = 0;
  11.     if (weight > 1 && weight <= lowRateLimit) {
  12.         totalPrice = lowRate * weight;
  13.     } else if (weight > lowRateLimit && weight <= midRateLimit) {
  14.         totalPrice = lowRate * lowRateLimit + midRate * (weight - lowRateLimit);
  15.     } else if (weight > midRateLimit) {
  16.         totalPrice = lowRate * lowRateLimit + midRate * (midRateLimit - lowRateLimit) + highRate * (weight - midRateLimit);
  17.     }
  19.     return totalPrice;
  21. }

备注：

  • 你的 else if 语句 else if (weight > 25 && weight < 75) 总是为假
  • 你定义了 rate 但没有使用它
英文:

I think what you are after is this

  1.   static int calculateLandingRate(int weight) {
  2. int lowRate = 26;
  3. int midRate = 53;
  4. int highRate = 79;
  5. int lowRateLimit = 25;
  6. int midRateLimit = 75;
  7. int totalPrice = 0;
  8. if (weight &gt; 1 &amp;&amp; weight &lt;= lowRateLimit) {
  9. totalPrice = lowRate * weight;
  10. } else if (weight &gt; lowRateLimit &amp;&amp; weight &lt;= midRateLimit) {
  11. totalPrice = lowRate * lowRateLimit + midRate * (weight - lowRateLimit);
  12. } else if (weight &gt; midRateLimit) {
  13. totalPrice = lowRate * lowRateLimit + midRate * (midRateLimit - lowRateLimit) + highRate * (weight - midRateLimit);
  14. }
  15. return totalPrice;
  16. }

Remarks:

  • Your elseif statement else if (weight&gt; 25 &amp;&amp; weight &lt; 75) is always false
  • you define rate but do not use it

  1. import java.util.Scanner;

  8.         weight = sc.nextInt();
  9.         b = calculateLandingRate(weight);
  10.         System.out.println("Total price  : " + b);
