在java中static 和void點解?

public static void main (String args[])

static 係指唔可以利用一個 instance method 去 override 一個 static 既 method.

void 係個 method 會 return 既 class type, void 代表唔會 return 任何野.

------------------

public void one_method ()
{
static int i;
...

呢個 static 係指 i 呢個整數只會嚮第一次行呢個 method 既時侯先會被 create 同 initialize.
當同一個 method 被執行第二次既時候就會用返第一次既 i, 而唔係重新 create 多另一個 i 出黎.

static applies to the whole class within that JVM, not an instance of a class.

static can be used in method, member variable etc.

void indicates the return type of the method. In this case, nothing is expected to be returned by the method.
