out.print(arr[i] + "\t");//66,55,44,33,22,11 } 方式2:使用逆序赋值方式 ArrayReverse02.java 思路1. 先创建一个新的数组 arr2 ,大小 arr.length 2. 逆序遍历 arr ,将 每个元素拷贝到 arr2的元素中(顺序拷贝) 3. 建议增加一个循环变量 j -> 0 -> 5 代码语言:javascript 代码运行次数:0 ...

A)The program runs fine and displays x[0] is 0. B)The program has a runtime error because the array elements are not initialized. C)The program has a runtime error because the array element x[0] is not defined. D)The program has a compile error because the size of the array wasn...
Program 2: Sort the elements of an Array in Descending Order In this approach, we will see how to use Arrays.sort() and Collections.reverseOrder() to sort an array in descending order. The Arrays class of ‘java.util’ package provides the sort method that takes an array as an argument...
There’s also a new method called reversed that returns a SequencedCollection that is a view on the underlying collection but in reverse order, which makes it super easy to iterate or stream over the collection. Copy code snippet Copied to Clipboard ...
11.Write a Java program to reverse an array of integer values. Click me to see the solution 12.Write a Java program to find duplicate values in an array of integer values. Click me to see the solution 13.Write a Java program to find duplicate values in an array of string values. ...
Resizable-array implementation of theDequeinterface. Array deques have no capacity restrictions; they grow as necessary to support usage. They are not thread-safe; in the absence of external synchronization, they do not support concurrent access by multiple threads. Null elements are prohibited. Thi...
