换句话说,它可以输入直到换行或换行并结束输入'n'或按回车。 以下是在 Java 中如何实现nextLine()方法的示例: importjava.util.Scanner;classgeekdocsDemo{publicstaticvoidmain(String[]args){// Creating the object of the// Scanner classScannersc=newScanner(System.in);// Use of nextLine() methodStringIn...
* int java.util.Scanner.nextInt() Scans the next token of the input as an int. * * An invocation of this method of the form nextInt() behaves in exactly the * same way as the invocation nextInt(radix), where radix is the default radix * of this scanner. * * Returns: the int ...
java中nextline用法 1. In Java, the `nextLine()` method is super useful for reading a whole line of text from the user. For example, I'm making a simple chat program. I want to let the user enter a full message. So, I use `Scanner` and `nextLine()`. It's like opening a door...
2 鉴于以上两种方法的只要区别，同学们一定要注意next（）方法和nextLine（0方法的连用，下面举个例子来说明：importjava.util.Scanner;publicclassNextTest{publicstaticvoidmain(String[]args){//TODOAuto-generatedmethodstubStrings1,s2;Scannersc=newScanner(System.in);System.out.print("请输入第一个字符串：");...
{ // TODO Auto-generated method stub String s1, s2; Scanner sc = new Scanner(System.in); System.out.println("请输入第一个字符串:"); s1 = sc.nextLine(); System.out.println("请输入第二个字符串:"); s2 = sc.next(); System.out.println("输入的字符串是:" + s1 + " " + s2);...

Advances this scanner past the current line and returns the input that was skipped. This method returns the rest of the current line, excluding any line separator at the end. The position is set to the beginning of the next line.
