实现字符串倒序的总结

public class Test{
    public static void main(String[] args){

        String str = "swiss";

        //charArray()和contains()①
        char[] temp1 = str.toCharArray();
        String temp2 = "";
        for(int x = 0;x0){
                        //取出0号位置的字符,加入新串,然后在老串删除该字符(自己想的,但是过后居然看不懂了,补个说明)
            String temp = str.charAt(0)+ "";
            System.out.print(temp);
            str = str.replace(temp,"");
        }
        System.out.println();
        //split() 和equals()
    }
}
