请各位大大看看这段代码错在哪里

没有main方法（估计是你把构造方法和main方法混写了）
public Gun(){
}
public static void main(String[]args ) {
        Gun g1=new Gun();
        Gun g2=new Gun();
        g1.name="沙鹰";
        g1.number=24;
        g2.name="awp";
        g2.number=30;
        System.out.println("名字:"+g1.name+"子弹数量"+g1.number);
        System.out.println("名字:"+g1.name+"子弹数量"+g2.number);
        // TODO code application logic here
    }
