ArrayDemo程序分配一个10个元素的数组,并赋值数组的引用给anArray变量。 // create an array of integers anArray = new int[10]; 如果声明缺失,编译器会报错,错误信息类似下面: ArrayDemo.java:4: Variable anArray may not have been initialized. 下面几行给数组的每个元素赋值: anArray[0] = 100; // ...

25.数组中有length()这个方法,如array.length()表示数组array中元素的个数[单选题]* 对 错(正确答案) 26.用任何方式创建数组时,都必须指定数组的长度[单选题]* 对(正确答案) 错 27.声明数组时,要指定数组长度,以便为数组分配内存[单选题]* 对 错(正确答案) 28.static可用来修饰局部变量[单选题]* 对 错...
Consider the following code where we create an array of length 5 and try to insert 7 elements in it. Whenever the array becomes full, we increase its size by using our increaseSize() method. public class Main { public static int[] increaseSize(int[] arr) { int[] newArr = new int[...
Anarrayis a container object that holds a fixed number of values of a single type. The length of an array is established when the array is created. After creation, its length is fixed. You have seen an example of arrays already, in themainmethod of the "Hello World!" application. This...
To determine the size of a Java array, query itslengthproperty. Here is an example of how to access the size of a Java array in code: int[] exampleArray ={1,2,3,4,5};intexampleArraySize = exampleArray.length; System.out.print("This Java array size is:" + exampleArraySize );//...
classArrayMethods{staticvoidMain(){// Create a string array of size 5:string[] employeeNames =newstring[5];// Read 5 employee names from user:System.Console.WriteLine("Enter five employee names:");for(inti=0; i<employeeNames.Length; i++) { employeeNames[i]= System.Console.ReadLine();...
