小弟刚刚学java，javac CatTestClassQ4。java的时候，老是说CatTestClassQ4.java:24: 无法将 Cat 中的 meow() 应用于 (int)
kittyTwo.meow(m); 大虾们帮帮忙，还有小弟乃初学者，解释的时候尽量白话一点-_-"

public class CatQ4 {
String name;
String colour;
int age;

public void meow( ){
System.out.println("meooooow");

}
public void meow(int m){
if (( m <= 9) && (m>0)) {
for( ; m>0 ; m--){
System.out.print("meooow! ");
}
}
else
System.out.print("Error!");

}

}




public class CatTestClassQ4{
public static void main(String[] args){
Cat kittyOne = new Cat();
kittyOne.name = "Tiger";
kittyOne.colour = "Orange and Black";
kittyOne.age = 5;
kittyOne.meow( );

int m = Integer.parseInt(args[0]);
Cat kittyTwo = new Cat();
kittyTwo.name = "Snowball";
kittyTwo.colour = "White";
kittyTwo.age = 2;
kittyTwo.meow(m);

}
}

你的kittyOne和kittyTwo对象是CatQ4的还是Cat的？Cat类根本不存在，而且你想重载方法那么参数列表对应了吗 你有无参的方法吗，而且最好通过构造方法来初始化它的成员变量,还有在Java一个包中只能有一个类是public
class Cat {
String name;
String colour;
int age;
Cat() {
}
public void meow() {
System.out.println("meooooow");
}
public void meow(int m) {
if (( m <= 9) && (m>0)) {
for( ; m>0 ; m--) {
System.out.print("meooow! ");
}
} else {
System.out.print("Error!");
}
}

}
public class CatTestClassQ4 {
public static void main(String[] args){
Cat kittyOne = new Cat();
kittyOne.name = "Tiger";
kittyOne.colour = "Orange and Black";
kittyOne.age = 5;
kittyOne.meow();
int m = Integer.parseInt(args[0]);
Cat kittyTwo = new Cat();
kittyTwo.name = "Snowball";
kittyTwo.colour = "White";
kittyTwo.age = 2;
kittyTwo.meow(m);
}
}
