How to solve Java array length exception (InvalidArrayLengthException)
In Java programming, array is an important data structure, which can be used to store and process large amounts of data. However, when we create or operate an array, we sometimes encounter an array length exception (InvalidArrayLengthException), which may cause the program to fail or produce incorrect results. The following describes how to resolve Java array length exceptions and provides corresponding code examples.
int maxLength = Integer.MAX_VALUE; int[] array = new int[maxLength];
import java.util.ArrayList; ArrayList<Integer> list = new ArrayList<Integer>(); // 增加元素到动态数组 list.add(10); list.add(20);
try { int[] array = new int[Integer.MAX_VALUE]; } catch (NegativeArraySizeException e) { System.out.println("数组长度异常:" + e.getMessage()); }
int maxLength = Integer.MAX_VALUE; assert maxLength > 0 : "数组长度超过限制"; int[] array = new int[maxLength];
To sum up, to solve the Java array length exception, we can take the following measures: check whether the array length exceeds the limit, use dynamic arrays instead of static arrays, and use try-catch statement to handle exceptions and verify array length using assertion statements. However, in actual programming, we should also choose the appropriate solution based on specific business needs and development environment.
We hope that the code examples and solution ideas provided in this article can help readers solve Java array length exceptions and improve the quality and reliability of the code in daily development work.
