我如何才能只为java的UVA在线问题接受字符串输入?需要详细信息

while(s = getchar()) {
if(s == EOF)
}

import java.util.Scanner;
Scanner scanner = new Scanner(System.in);
System.out.println("Enter a string.");
String str = scanner.nextLine();

这就是你要找的吗？如果你正在读取文件，

import java.io.File;
Scanner scanner = new Scanner(new File("path.txt"));
while (scanner.hasNextLine()) {
String str = scanner.nextLine();
//...
}

Scanner stdin = new Scanner(System.in);
while (stdin.hasNextLine()) 
{
String line = stdin.nextLine();
// Further Opera
}
