所以语句“Object o”是Java继承中多态的体现,同样,indexOf中的equals()方法实际上也是在用String类对象来调用String类中的equals方法。 10、remove(int index) 方法 remove(int index)方法用于移除列表中指定位置的元素,并返回被删元素 package runtime; import java.util.ArrayList;//因为ArrayList来自于java.lang包...

Get Index of an Array Element Using Java 8 Stream API in Java In Java, you can use the Stream API to efficiently filter out elements from an array and determine the position of a specified element. Specifically,IntStreamis an interface that allows you to perform Stream operations on primitive...
JAVA的array中indexOf 记得龙哥有个重构的文章里说直接判断啥的。 今天看JDK ArrayList,看到了他的 indexOf,他先判断,后进入循环,看似写了两遍for 循环,但是简单明了暴力。i like it . publicclassTest {publicstaticvoidmain(String[] args) { } Object[] elementData;privateintsize;publicintindexOf(Object ...
