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：");...
* 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 ...

For simplicity, we’ll use unit test assertions to verify results in this tutorial. First, let’s get the number 42 using theScanner.nextLine()method: Scannersc1=newScanner(input);intnum1=Integer.parseInt(sc1.nextLine()); assertEquals(42, num1);Copy ...
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.nextInt() 方法会读取下一个 int 型标志的 toke 4、n. 但是焦 点不会移动到下一行, 仍然处在这一行上。 当使用 nextLine() 方法时会读取改行剩余...
Java String Scanner input does not wait for info, moves directly to next statement. How to wait for info? 20 Why is nextLine() returning an empty string? 10 Why can't I enter a string in Scanner(System.in), when calling nextLine()-method? 14 Can't use Scanner.nextInt() and ...
