FormalParameterList无效，令牌“。”上的语法错误，{此标记后的预期

Question

如何修复此声明？

System.out.printf("    1     |    %d     |   %d |   %d\n" , 
                    Simulator.simulate(2, 1, 0.71, 15, 1200), 
                    Simulator.simulate(5, 1, 0.71, 15, 1200), 
                    Simulator.simulate(10, 1, 0.71, 15, 1200)      
                  );

Syntax error on token ".", { expected after this token [. in Simulator.simulate]

Syntax error on token ""    1     |    %d     |   %d |   %d\n"", invalid FormalParameterList

Answer 1

以下代码会创建完全相同的错误（以及更多错误）

public class Analyzer {
   System.out.printf("    1     |    %d     |   %d |   %d\n" , 
                Simulator.simulate(2, 1, 0.71, 15, 1200), 
                Simulator.simulate(5, 1, 0.71, 15, 1200), 
                Simulator.simulate(10, 1, 0.71, 15, 1200)      
              );
}

类主体中的方法调用System.out.printf 不允许。在方法，构造函数或静态初始化程序中移动它：

public class Analyzer {
   static {
     System.out.printf("    1     |    %d     |   %d |   %d\n" , 
                Simulator.simulate(2, 1, 0.71, 15, 1200), 
                Simulator.simulate(5, 1, 0.71, 15, 1200), 
                Simulator.simulate(10, 1, 0.71, 15, 1200)      
              );
   }
}
