每当我在cmd中通过JAVAC命令编译上面的代码时,它只给出第一个错误意味着不给出第二个错误。在 java 语言中,部分编译器和部分解释器以及在 java 中第一次编译发生,所以编译器应该列出所有错误,但它只给我一个错误。为什么会这样?我不明白所以请帮我解决这个问题..
我想现在我很清楚我的问题意味着编译器完全可以工作......
为此,我创建了一个简单的示例,它将帮助您了解 java 编译器的工作原理。
class TestCompilation
{
public static void main(String []args)
{
Syste.out.rintln("Hello");//First Error
Syste.Out.rintln("Hello");//Second Error (Not printed at compiler time because it syntatically correct as in compiler first phase)
Hitesh542.add(); //there is no such class called Hitesh542.- but compiler thinks that it is right way to call the method. So it passes the first time.
Hitesh542.add()();//Look out here.. There is a problem, that we can't call a method like this..So it will show the error on first lookup.
System.otu.println("Hello")//second Errorasdasdas
if(); //look this is also an error.- A BASIC syntax error shown at the first lookup.
try{
int i = 10 / 0;
}
//Third error
//So bottom line is the JAVA syntatical errors are checked first i.e The SYNTAX of JAVA not the classes or objects.
//But obv is the first thing is Java Compiler should get the Java class first for compilation on proper path. :)
