Why is the string "Hello" entered by Scanner(System.in) printed incorrectly after calling func(str2)?
The java code is as follows：
package test;
import java.util.Scanner;
public class TestCodePoint
{
private static void func(String str)
{
System.out.println("after: " + str);
}
public static void main(String[] args)
{
String str = "Hello";
System.out.println("before: " + str);
func(str);
System.out.print("Please input a string: ");
Scanner sc = new Scanner(System.in);
String str2 = sc.next();
System.out.println("str2_before: " + str);
func(str2);
}
}
The result of the implementation is:
before: Hello
after: Hello
Please input a string: Hello (Here is the paste input)
str2_before: Hello
after: ��Hello
Why is the output of the last one "��Hello" instead of "Hello"?
