比较整数和字符串数组并得到相应总和的Java代码

Question

有两个字符串数组，array1 和 array2。
String[] array1 = {"1", "2", "3", "4","5","6","7"}
String[] array2= {"苹果", "", "", "香蕉", "", "", "橙子"}; 你能帮我写一段java代码来产生类似的输出吗？

字符串[]desiredOutput = {“1”，“5”，“4”，“11”，“7”}

逻辑：array2中只要有空值，就添加array1中对应的值

示例： array2[0] = "apple"，因此所需的输出是 array1[0] 的值，输出 ={"1"} array2[1] = "" 和 array2[2] = "" 因此所需的输出是 (array1[1]+array1[2]) 的总和，输出 ={"1","5"} array2[3] = "banana"，因此所需的输出是 array1[3] 的值，输出 ={"1","5","4"} array2[4] = "" 和 array2[5] = "" 因此所需的输出是 (array1[4]+array1[5]) 的总和，输出 ={"1","5","4","11"} array2[6] = "orange"，所以所需的输出是 array1[6] 的值，输出 ={"1","5","4","11","7"}

谢谢

它尝试过这个，。但失败了 String[] array1 = {"1", "2", "3", "4", "5", "6", "7"}; String[] array2 = {"苹果", "", "", "香蕉", "", "", "橙子"};

     // Calculate concatenated values and add them to a new array
     String[] concatenatedArray = new String[array1.length];
     for (int i = 0; i < array1.length; i++) {
         int value1 = Integer.parseInt(array1[i]);
         int value2 = (array2[i].isEmpty()) ? 0 : Integer.parseInt(array2[i]);
         concatenatedArray[i] = String.valueOf(value1 + value2);
     }

     // Print the concatenated array in the desired format
     System.out.print("(");
     for (int i = 0; i < concatenatedArray.length; i++) {
         System.out.print("\"" + concatenatedArray[i] + "\"");
         if (i < concatenatedArray.length - 1) {
             System.out.print(",");
         }
     }
     System.out.println(")");

您必须添加 array1[] 元素，直到在 array2[] 中找不到非空元素为止，当满足此条件时，只需替换结果列表中的最后一个索引元素即可。

我相信这就是您正在寻找的

    String[] array1 = {"1", "2", "3", "4", "5", "6", "7"};
    String[] array2 = {"apple", "", "", "banana", "", "", "orange"};
    List<String> result = new ArrayList<>();
    int sum=0;
    for (int i = 0; i < array1.length; i++) {
        if(array2[i].length() > 0){
            sum=0;
            result.add(array1[i]);
        }
        else{
            if(sum != 0){
                sum += Integer.parseInt(array1[i]);
                result.set(result.size()-1, String.valueOf(sum));
            } else{
                sum += Integer.parseInt(array1[i]);
                result.add(String.valueOf(sum));
            }
        }
    }
