求帮忙，counter的值是如何变化的
public class Mix4{
int counter = 0;
public static void main( String [] args){
int count = 0;
Mix4 [] m4a = new Mix4[20];
int x = 0;
while(x < 2){
m4a[x] = new Mix4();
m4a[x].counter = m4a[x].counter + 1;
count = count + 1;
count = count + m4a[x].maybeNew(x);
x = x+1;
}
System.out.println(count+" "+m4a[1].counter);
}
public int maybeNew(int index){
if(index<1){
Mix4 m4 = new Mix4();
m4.counter=m4.counter+1;
return 1;
}
return 0;
}
}
输出结果：3 1
