Transcribed Image Text:Write a program that reads two lists of integers from input into two arrays and outputs the sum of multiplying the corresponding list items. The program first reads an integer representing the length of each list, followed by two lists of integers. Ex: If the input is: 3 1 2 3 3 2 1 the program calculates (1 * 3) + (2 * 2) + (3 * 1) and outputs 10 Ex: If the input is: 2 3 4 5 1 1 1 1 the program calculates (2 * 1) + (3 * 1) + (4 * 1) + (5 * 1) and outputs 14

Transcribed Image Text:This image illustrates an error encountered in a Java program due to the misuse of the `Scanner` class. The section at the top shows the Java code, which appears to be working on a mathematical computation involving two arrays `a` and `b`. Here’s a breakdown of each segment: ### Java Code: - The code initializes variables and inputs data to perform mathematical operations. - Key sections include the calculation of a `sum`, where each pair of elements from two arrays (`a` and `b`) are multiplied and accumulated. ### Inputs and Errors: - Users are instructed to enter inputs in the provided box. Example inputs shown are `1 2 3` and `3 2 1`. - When attempting to run the program, users encounter `Program errors displayed here`: #### Error Details: 1. **Error Message:** - `LabProgram.java:11: error: cannot find symbol len = sc.nextInt();` - **Symbol**: variable `sc` - **Location**: class `LabProgram` 2. **Repetitive Errors:** - Similar errors occur at line 15 and line 18, indicating `sc` is used without being properly initialized. 3. **Nature of Errors:** - The errors suggest that the `Scanner` object `sc` has not been declared. This is essential for capturing user input in Java programs. - Solution: Declare `Scanner sc = new Scanner(System.in);` at the beginning of the class to resolve these errors. ### Workflow Diagram: - A workflow diagram illustrates the flow from input gathering to processing through `LabProgram.java` and output generation. ### Conclusion: These errors need addressing by declaring and initializing the `Scanner` object properly so that inputs can be read and processed without issues. Understanding these common mistakes is crucial for beginners learning Java programming.
