方法一：使用StringBuilder
import java.util.Scanner;
public class StrReversal {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String str = scanner.nextLine();
System.out.println(new StringBuilder(str).reverse());
}
}
方法二：使用循环
import java.util.Scanner;
public class StrReversal {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String str = scanner.nextLine();
char[] chars = str.toCharArray();
String reverse = "";
for (int i = chars.length - 1;i>=0;i--){
reverse += chars[i];
}
System.out.println(reverse);
}
}
方法三：考虑到String不可变，使用StringBuilder
import java.util.Scanner;
public class StrReversal {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String str = scanner.nextLine();
char[] chars = str.toCharArray();
StringBuilder reverse = new StringBuilder();
for (int i = chars.length - 1;i>=0;i--){
reverse.append(chars[i]);
}
System.out.println(reverse);
}
}
