import java.util.Scanner; public class Ex3_2 {       public static void main(String afe[]){              String putIn = “The past is gone and static. Nothing we can do will change it. Thefuture is before us and dynamic. Everything we do will affect it.”              char findChar,temp;              int num = 0; Scanner input=new Scanner(System.in);              System.out.println("请输入要查找的字符：");              findChar = input.next().charAt(0);               for(int i = 0;i<putIn.length();i++){                     temp = putIn.charAt(i);                     if(temp == findChar){                            num++;                     }              }              System.out.println("字符串"+putIn+"中包含"+findChar+"个数为："+num);       }      }
