Question

在java里输入一句话怎么让它倒序输出

Answer 1

将字符串倒叙输出有多种方式，下面我罗列两种以作参考：
方法一：利用String类的toCharArray()，再倒序输出数组。
public class javatest {
　　public static void main(String[] args) {
　　 String originalString = "abcdefg";
String resultString = "";
char[] charArray = originalString.toCharArray();
for (int i = charArray.length-1; i>=0; i--){
resultString +=charArray[i];
}
System.out.println(resultString);
}
}

方法二：使用reverse()方法
public class reverseTest {
public static void main(String[] args) {
String originalString = "abcdefg";
StringBuffer stringBuffer = new StringBuffer(originalString);
System.out.println(stringBuffer.reverse());
}
}

Answer 2

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;

public class Test {
public static void main(String args[]) throws IOException {
BufferedReader br = new BufferedReader(new InputStreamReader(System.in)) ;
StringBuffer sb = new StringBuffer() ;
System.out.println( "输入:") ;
char[] c= br.readLine().toCharArray() ;
for(int i=c.length-1;i>=0;i--){
sb.append(c[i]) ;
}
System.out.print("倒叙输出为=="+sb) ;
}
}
