上面的就是我所出现的错误!初学java请大家多多关照.

Answer 3

public class void main
改成 public static void main改一个地方就好了

Answer 4

public class void main(String[] args){==>public static void main(String[] args){

Answer 5

老弟失误不好意思呀
大家给我讲讲类包吧为什么?????"""||package numberstring;
 
public class numbertobinarystringdemo{
   public static void main(String[] args){
        int int1=55;
        System.out.println("Integer.toBinaryString(int1)="   +  Integer.toBinaryString(int1));
        long long1=252;
        System.out.println("Long.toBinaryString(Long1)="   +  Long.toBinaryString(long1));
        System.out.println("Integer.toOctalString(int1)="    +  Integer.toOctalString(int1));
        System.out.prin
把package numberstring;去掉就没有问题.........
