//將String 對象轉(zhuǎn)換為可改變的StringBuffer類對象

//然后調(diào)用StringBuffer類的reverse()方法實(shí)現(xiàn)反轉(zhuǎn)

String strReverse=new StringBuffer(str).reverse().toString();

System.out.println(strReverse);

}

如何實(shí)現(xiàn)一個(gè)字符串的置逆（java）

我們可以通過運(yùn)用JAVA的?StringBuffer的1字符串反轉(zhuǎn)方法直接置逆，下面將舉例說明：

public?class?Test?{

public?static?void?main(String[]?args){

String?str?=?"12345678";

System.out.println(str);

//聲明一個(gè)緩沖字符串

StringBuffer?sb?=?new?StringBuffer(str);

//通過reverse()反轉(zhuǎn)方法，反轉(zhuǎn)；然后轉(zhuǎn)換成字符串

str?=?sb.reverse().toString();

System.out.println(str);

}

}

編寫一個(gè)JAVA程序,把一個(gè)字符串反過來顯示

public AbstractStringBuilder reverse() {

boolean hasSurrogate = false;

int n = count - 1;

for (int j = (n-1) 1; j = 0; --j) {

char temp = value[j];

char temp2 = value[n - j];

if (!hasSurrogate) {

hasSurrogate = (temp = Character.MIN_SURROGATE temp = Character.MAX_SURROGATE)

|| (temp2 = Character.MIN_SURROGATE temp2 = Character.MAX_SURROGATE);

}

value[j] = temp2;

value[n - j] = temp;

}

if (hasSurrogate) {

// Reverse back all valid surrogate pairs

for (int i = 0; i count - 1; i++) {

char c2 = value[i];

if (Character.isLowSurrogate(c2)) {

char c1 = value[i + 1];

if (Character.isHighSurrogate(c1)) {

value[i++] = c1;

value[i] = c2;

}

}

}

}

return this;

}

這就是StringBuffer類中reverse方法的源代碼.這就是原理!

java 如何實(shí)現(xiàn)一個(gè)字符串的反轉(zhuǎn)

package string;

public class StringTest3 {

public static void main(String[] args)

{

String s="abcdefg";

String s2="";

char[] cs=s.toCharArray();

for(int i=cs.length-1;i=0;i--)

{

s2=s2+cs[i];

}

System.out.println("對字符串進(jìn)行反轉(zhuǎn)操作后為:"+s2);

StringBuffer sb=new StringBuffer("abcdefg");

StringBuffer sb2=sb.reverse();

System.out.println("對StringBuffer進(jìn)行反轉(zhuǎn)操作后為:"+sb2);

}

}

Java中如何實(shí)現(xiàn)字符串反轉(zhuǎn)？

反轉(zhuǎn)：

public class test{

public static void main(String[] args) {

Scanner input = new Scanner(System.in);

System.out.print("請輸入：");

String s1 = input.nextLine();//得到輸入的字符e5a48de588b6e799bee5baa6e997aee7ad9431333363396464串

System.out.print("翻轉(zhuǎn)后：");

for(int i=s1.length()-1;i=0;i--){

System.out.print(s1.charAt(i));

}

}

}

或者

import java.util.*;

public class StringChange{

public static void main(String[] args){

System.out.println("Please enter the String:");

String str = new Scanner(System.in).nextLine(); //輸入字符串

String s2[] = str.split("\\s"); // \s 以空格為分隔符拆分字符串,并保存到數(shù)組s2里面

for (int i = s2.length-1; i = 0; i--) { //反向輸出數(shù)組

System.out.print(s2[i]+" ");

}

}

}
