not a statement java_java 编译错误 not a statement

importjava.util.Scanner;publicclassMain{intcount,n,k,pa,pb=0;Arraylista=newArraylist();Arraylistb=newArraylist();Scannersc=newScanner(System.in);intn=sc.nextInt();publicv...

import java.util.Scanner;

public class Main{

int count,n,k,pa,pb=0;

Arraylist a=new Arraylist();

Arraylist b=new Arraylist();

Scanner sc = new Scanner(System.in);

int n = sc.nextInt();

public void working(){

for (int i=1; i++; i<=n);

a.add(sc.nextInt());

for (int j=1; j++; j<=n)

{

b.add(sc.nextInt());

}

while ((pa!=pb) || (pa==0) )

{

pa=+a.get(count);

pb=+b.get(count);

count++;

}

System.out.print(count);

}

}

这是我写的代码，编译结果是

We received the following errors:

/grader/1/225444/compile/Main.java:12: error: not a statement
