The following example uses the Java Scanner class to take String input from the user: importjava.util.Scanner;public classScannerUserInput {public static voidmain(String[] args) {// String input with the Java ScannerSystem.out.println("How old are you?"); ScannerstringScanner=newScanner(System...
//我的菜鸡操作 String input = scanner.nextLine(); String[] a = input.split(" "); int[] b = new int[a.length]; for(int i = 0; i < a.length; i ++){ String aString = a[i]; b[i] = Integer.parseInt(aString); } 查看原帖 点赞 4 相关推荐 05-07 21:13 已编辑 门头沟学院...
To read a string from Console as input in Java applications, you can useScannerclass along with theInputStream,System.in. When you are developing console applications using Java, it is very important that you read input from user through console. In this tutorial, we will learn how to prompt...
UsingScannerInput andprintlnMethod to Print a String in Java Here, we use theScannerclass to get input from the user. We create an object of theScannerclass, and we ask the user to enter his name using theprint()method. We call thenextLine()method on theinputobject to get the user’s...

如果我们没有在子类中,给基类进行各类构造器的调用。那么它就会默认的调用基类的默认构造器。这很多时候会给我们带来困扰。因为我们从基类继承而来的子类。也希望能够调用基类的各类构造器而不仅仅是默认构造器。 下面的代码我自己定义了构造器, 所以应该是不存在默认构造器的。但是万一就存在了呢?现在看来把问题看严重...
