Java在变量名中区分大小写

public class Main {

  public static void main(String arguments[]) {

    int MyVar;
    /**
    时 代 J     a    v  a - nowjava.com
    **/

    // myvar variable is different from MyVar

    int myvar = 0;



    // Generate a syntax error at compile time:

    // cannot find symbol variable myVar

    // System.out.println(myVar);

    

    System.out.println(myvar);

  }

}
