GUAVA (GOOGLE Common Libraares) The best practice of the original type processing

Guava (Google Common Libraries) is a set of Java libraries developed by Google, which provides many convenient and efficient functions.In Guava, there are many useful tools and methods to handle primitive types (Primitive Types).This article will introduce some of the best practices of Guava and how to use these tools to handle the original type. There are two important classes in Guava to handle the original types: `ints` and` doubles.These classes provide many static methods to perform various operations related to the original types, such as conversion, comparison and search. First, let's see a simple example to show how to use Guava to process the original type: import com.google.common.primitives.Ints; public class PrimitiveExample { public static void main(String[] args) { int[] numbers = {5, 2, 8, 1, 9, 3}; // Use the Guava method to find the maximum and minimum values int max = Ints.max(numbers); int min = Ints.min(numbers); // Use the Guava method to convert the array to list List<Integer> numberList = Ints.asList(numbers); System.out.println("Max number: " + max); System.out.println("Min number: " + min); System.out.println("Number List: " + numberList); } } In the example above, we use the `Max () and` min () `methods of the` INTS` class to find the maximum and minimum value in the array.We then use the `Aslist ()` method to convert the original type array to `list`. In addition to these basic functions, Guava also provides many other useful methods.For example, you can connect the original type array as a string with the `Join ()` method of the `ints` class, or convert the` list` method by using the `ints.toarray ()` method to the original type array. Another useful feature is the `compare () method of the` ints` and `Doubles` class, which is used to compare the size of the two original type values.This is more efficient than the comparison methods in the Java standard library (such as `Integer.compare.compare () and` Double.compare () `). In addition, Guava also provides sorting and finding methods for primitive types.You can use the `contains ()" method of the `ints` and` doubls` class to check whether there is a certain value in the array, or use the `Indexof () method of the` ints` classEssence To sum up, Guava provides many useful tools and methods to handle the original type.They not only provide more efficient operations, but also provide more concise and easy -to -use APIs.By using the original type processing function of Guava, you can easily process and operate the original type data.
