能的,比如云脉的车牌识别系统的API开发就可以支持Java、C++、C、object pascal及 objective-C等多种语言。
public static void main(String[] args){
Scanner sc = new Scanner(System.in);
boolean flag = false;
System.out.println("请输入车牌号!");
do{
String carNumber = sc.next();
flag = carNumber.matches("(?i)^(CA|AZ|CO)[0-9]{4}$");
if(!flag){
System.out.println("车牌号不正确,请重新输入!");
}else{
System.out.println("车牌号正确!车牌号为:"+carNumber.toUpperCase());
}
}while(!flag);
}
public static void main(String[] args) {
String str= "";
int n=0;
int c=0;
for (int i = 0; i 7; i++) {
if(flag()){
c++;
str+=c4? charA():charB();
continue;
}
n++;
str+=n5? charB():charA();
}
System.out.println(str);
}
private static boolean flag(){
int i=(int) (Math.random()*1000);
return i%2==0;
}
private static String charA(){
return ""+(char)(Math.random()*26+'A');
}
private static String charB(){
return ""+(int)(Math.random()*10);
}
