12.nextLine()AfternextXXX()Methods Typically, thenextXXX()methods don’t consume the newline character in the input created by hitting the “Enter” key. For instance,callingnextInt()will only read the next integer value and doesn’t read the newline character. So, when we subsequently call...
The findInLine(java.lang.String), findWithinHorizon(java.lang.String, int), and skip(java.util.regex.Pattern) methods operate independently of the delimiter pattern. These methods will attempt to match the specified pattern with no regard to delimiters in the input and thus can be used in spe...
In Java, we can use bothInteger.parseInt(Scanner.nextLine())andScanner.nextInt()to read integers from aScanner. However, there are some differences between these two methods. In this tutorial, we’ll compare them and discuss their differences. 2. Reading Integers UsingInteger.parseInt(scanner.ne...
我一直在获取错误Obsolete Methods on the Stack,并警告当我运行没有错误的非常基本的程序时,它可能会导致虚拟机出现问题。我运行了一个只有类和主方法的程序,我得到了这个错误。在错误框之后,bug引用了main方法,但是我知道语法是正确的,因为我使用了Eclipse的main方法。import java.util.Scanner; public static void...
intnumber =in.nextInt(); String string=in.nextLine();floatreal =in.nextFloat(); String string2=in.nextLine(); and the data shown above, string would contain ≥23≤ and string2 would contain the empty string. Here is a program that uses these methods, followed by the output. Look over...

This is by far the easiest way to avoid problems--don't mix your "next" methods. Use onlynextLine()and then parseints or separate words afterwards. Also, make sure you use only oneScannerif your are only using one terminal for input. That could be another reason for the exception. ...
