Talk is cheap,show me your code. 嗯,还是来看代码吧: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 public class TreeSetTest { public static void main(String[] args){ TreeSet<String> treeSet = new TreeSet<>(); treeSet.add("Frank"); treeSet.add("Alice"); treeSet.add("Bob");...
public int hashCode() Java Copy参数: 此函数没有参数。返回: 该方法返回一个整数值,即TreeSet实例的hashCode值。下面的例子说明了TreeSet.hashCode()方法。例1 :// Java code to demonstrate the working of // hashCode() method in TreeSet import java.util.*; public class GFG { public static void ...
