package nameyu;public class Test {

    public static void main(String[] args) {

        // TODO Auto-generated method stub

    char ch1=(char) (65+Math.random()*26);

    char ch2=(char) (65+Math.random()*26);

    char ch3=(char) (65+Math.random()*26);

    String str1=String.valueOf(ch1);

    String str2=String.valueOf(ch2);

    String str3=String.valueOf(ch3);//把字符转换为字符串

    int  number1=(int) (Math.random()*10);

    int  number2=(int) (Math.random()*10);

    int  number3=(int) (Math.random()*10);

    int  number4=(int) (Math.random()*10);//  String str=str1+str2+str3;

    System.out.println(str1+str2+str3+" "+number1+number2+number3+number4);

    }

}
