Java programmers learn php-13. value passing is the same as passing a reference to php and Java. when calling a function, the basic data type is passed with a value, and the object is passed with a reference. However, php can also pass a reference to the basic data type (with amp; symbol): $ w65; functionchange_it ( amp; $ weight) {$ weight60;} change_it ($ w); ec java programmers learn php-13. value Transfer and reference

3. The value is also restricted, but cross-origin is supported.
Ii. ASP. NET page value

passes the reference copy to the str in the changeStr method. There are also two references here, but they are made in the changeStr method, str + = "haha"; action. Note that str in changeStr no longer points to "test", but to "testhaha". The two references point to different spaces, the printed value does not change.
Finally, let's take a look at a small example.
public static void main(String[] args) {StringBuffer sb = new StringBuffer("test2");System.out.println("Before = " + sb);change
