When you need to add elements of one list to another list without changing the original list, you can use the source list to target list in Java function. This may be used in a variety of situations, such as:
Data merging: When you need to merge data from two or more lists into one list, you can use the method of adding the source list to the target list.
Data filtering: When you need to filter out qualifying elements from a list based on certain conditions and add them to another list, you can use the method of adding the source list to the target list.
Data migration: When you need to migrate data from one list to another, you can use the method of adding the source list to the target list.
Data backup: When you need to back up the data in a list and add them to a new list, you can use the method of adding the source list to the target list.
In short, when you need to add elements from one list to another list while keeping the original list unchanged, you can use the method of adding the source list to the target list.
The following is an example of how FuncGPT (Human Function) adds the source list to the target list:
package com.feisuanyz.function;
import com.feisuanyz.flow.core.cmpt.annotation.function.MethodDesc;
import com.feisuanyz.flow.core.cmpt.annotation.function.ParamDesc;
import java.util.List;
public class ListUtils {
@MethodDesc(desc = "将源列表中的元素添加到目标列表中",
params = {
@ParamDesc(name = "sourceList", desc = "源列表"),
@ParamDesc(name = "targetList", desc = "目标列表"),
@ParamDesc(name = "<T>", desc = "列表中元素的类型"),
})
public static <T> void addToList(List<T> sourceList, List<T> targetList) {
if (sourceList == null || targetList == null) { // 检查入参是否为null
throw new IllegalArgumentException("Source list and target list cannot be null"); // 抛出异常，入参不能为空
}
targetList.addAll(sourceList); // 将源列表中的元素添加到目标列表中
}
}So for the above code, let’s see what Wen Xinyiyan’s evaluation is?
This code is a Java tool class whose function is to add elements from one list (sourceList) to another list (targetList). Here is my review of this code:
1. Generics are used: public static <T> void addToList(List<T> sourceList, List<T> targetList), which allows this function to handle any type of list, not just lists of specific types. . Improved code reusability.
2. Parameter checking: At the beginning of the function, the code checks whether the two input lists are null. If either list is null, an IllegalArgumentException is thrown. This avoids NullPointerException at runtime.
3. Annotations are used: The @MethodDesc and @ParamDesc annotations in the code provide a detailed description of the function, which is very helpful for understanding the purpose of the function and the role of the parameters, especially for those who read your code.
4. Concise and clear: The function of the function is very clear, which is to add elements of the source list to the target list. The code is concise and easy to understand.
5. The function is static: This means that you do not need to create an instance of this class to use this function, making it more convenient to use.
Overall, this is a very well-written function that is clear, concise, safe (has parameter checks) and easy to use (static function).
It is reported that FuncGPT (FuncGPT) supports the creation of all types of functions. Use natural language to describe Java function requirements and generate high-quality, highly readable Java function code in real time. The generated code can be directly copied to IDEA, or imported into the Java fully automatic development tool function library with one click.
FuncGPT (FuncGPT) five major capabilities:
1. Natural language: Functions can be generated through natural language, lowering the threshold for software development.
2. Second-level function development: Fully automatic second-level function development, completed in seconds, and efficiency increased by a thousand times.
3. One-stop function development and application: functions can be directly applied after generation, with guaranteed efficiency and safety.
4. Reliable quality: The generated function code complies with industry standards, has good readability, and is consistent with the optimal solution.
5. Flexible generation: It can be generated according to the specific needs of developers and supports adjustments and modifications.
