}


发现不了语法错误，可是编译就是通不过。。。。

[解决办法]
/*数据成员的初始化过程*/
public class InitSequence{
Tools ts1=new Tools();//你少个;

public static void mian(String[] args){
System.out.println("call Tools.t4.f(4) in main()");
Tools.t4.f(4);
System.out.println("Creating new Tools() in main()");
new Tools;//new Tools();
System.out.println("Creating new InitSequence() in main()");
new InitSequence();
}
