举个例子: Scannerscanner=newScanner(System.in);System.out.print("请输入一个整数:");intnum=scanner.nextInt();// 和next一样System.out.print("请输入一行字符串:");Stringline=scanner.nextLine();System.out.println("输入的整数为:"+num);System.out.println("输入的字符串为:"+line); 输入: 10...
} String Line = "This is my first java program";String[ ] s = Line.split(" ");String head = s[0]+s[1];String tail = s[2]+s[3]+s[4]+s[5];System.out.println(head);System.out.println(tail);String Line = "This is my first java program"；String[] ss = Lin...
next Line()读取结果为String类型 区别二 读取方式 next(),nextInt(),nextFloat()看到空格符或回车符都认为读取结束,此时不会读取回车符。 nextLine()只以回车符为结束,并且会读取回车符。 请看以下例子: publicvoidlogIn(){ Scanner input =newScanner(System.in); System.out.println("请输入ID:"); intid ...

下面看下nextLine()的用法,还是使用同样的代码,只是需要修改下s.netLine() package WorkStudy; import sun.rmi.runtime.Log; import java.util.Scanner; public class ScannerTest { public static void main(String[] args) { System.out.println("为nextLine()准备的值: "); ...
发现我在用Scanner函数时,在字符串中加入空格,结果空格后面的东西没有输出来(/尴尬),不多说直接上代码: import java.util.Scanner; //Scanner中nextLine()方法和...next()方法的区别 public class ScannerString { public...
String str=sc.nextLine(); System.out.println("输出的内容为:"+str); //凡是输入IO流(后面会讲到)的类,用完不关闭就会一直占用资源 sc.close(); } } 输出结果: 输入数据: 45 输出的内容为:45 用Scanner实现字符串的输入有两种方法,一种是next(),一种nextLine(); Scanner中next()方法与nextlLine()方...
