可以使用Java的Scanner类来实现: importjava.util.Scanner;publicclassMain{publicstaticvoidmain(String[]args){// 创建Scanner对象Scannerscanner=newScanner(System.in);// 提示用户输入字符串System.out.print("请输入字符串:");// 接收用户输入的字符串Stringinput=scanner.nextLine();// 关闭Scanner对象scanner.c...
In Java, thetrim()method is used to remove leading and trailing whitespace from a string. Whitespace includes spaces, tabs, and newline characters. Thetrim()method returns a new string with the leading and trailing whitespace removed. This article explains how thetrim()method works and provides...
