从键盘接受一个字符串(String)，并将其转换为字符型(char)

之前做过从键盘接受一个字符串并将其转换为Integer型，当时用了函数parseInt()

昨天遇到要将其转换为char型的问题，却发现没有类似的转换函数，后来发现只需使用charAt()函数即可

package primary;import java.io.BufferedReader;import java.io.IOException;import java.io.InputStreamReader;public class StringToChar {/** * @param args */public static void main(String[] args) {// TODO Auto-generated method stubInputStreamReader isr = new InputStreamReader(System.in);BufferedReader br = new BufferedReader(isr);System.out.println("Please input a string: ");try {char c = br.readLine().charAt(0);System.out.println("The character is " + c);}catch(IOException e) {e.printStackTrace();}finally {System.out.println("God bless you.");}}}
