main函数同时打印if和else中的内容

/**
 * Created by admin 
 */
public class Test{
    public static void main(String[] args){
   /*     if(args==null||new Test(){{Test.main(null);}}.equals("abcde")){
            System.out.println("a");
        }else{
            System.out.println("b");
        }*/

        if(System.out.printf("a")==null){
            System.out.println("a");
        }else{
            System.out.println("b");
        }

    }
}
