Java 对字符以及字符数组的操作

import java.util.Scanner; public class test1 {public static void main(String[] args) {ff3(); // 只调用ff3()方法}//输出字符串public static void ff() {String sstring = "你是一个好男人！";System.out.println(sstring);}//字符串转换成数组，，输出数组和ASCLLpublic static void ff1() {       String sstring = "you are a good man";char cc[] = sstring.toCharArray();for (int i = 0; i < cc.length; i++) {System.out.println(cc[i] + " " + (int) (cc[i]));}}//接收键盘数据，输出数组和ASCLLpublic static void ff2() {Scanner sscScanner = new Scanner(System.in);String sstrString = sscScanner.next();System.out.println(sstrString);}// 接收键盘输入 的字符串，转换成数组，输出ASCLLpublic static void ff3() { System.out.println("输入需要转换的字符串");Scanner sscScanner1 = new Scanner(System.in);String sstrString1 = sscScanner1.next();char cchar[] = sstrString1.toCharArray();for (int i = 0; i < cchar.length; i++) {System.out.println(cchar[i]+"-->"+(int)cchar[i]);}}}
