【語言比較】1.class

JAVA

class:

class a01{

private int x;

int y;

public void setx(int x){

this.x = x;

}

public int getx(){

return this.x;

}

public int area(){

return this.x * this.y;

}

使用

a01 a = new a01();

a.setx(10);

a.y = 20;

system.out.print(a.area());

ObjectiveC

a01.h檔

@property int x,y;

- (void) setx:(int)x;

- (int) getx();

- (int) area();

a01.m檔

@synthesize x,y;

- (void) setx:(int)setX{

x = setX;

}

- (int) getx(){

return x;

}

- (int) area(){

return x*y;

}

使用

a01 *a = [[a01 alloc] init]

[a setx:10]

a.y = 20;

NSLog(@"%i",[a area]);

PHP

class:

class a01{

private $x;

public $y;

public function setx($x){

$this->x = $x;

}

public function getx(){

return $this->x;

}

public function area(){

return $this->x * $this->y;

}

使用

$a = new a01();

$a->setx(10);

$a->y = 20;

echo $a->area();

Javascript (網頁)

class:

function a01() {

this.x;

this.y;

this.setx = function(x) {

this.x = x;

}

this.getx = function(){

return this.x;

}

this.area = function(){

return this.x * this.y;

}

使用

var a = new a01();

a.setx(10);

a.y = 20;

document.write(a.area());

【mysql】不常用語法

1. is Null
SELECT * FROM user WHERE address is Null

2.is not Null
SELECT * FROM user WHERE address is not Null

3.not like
SELECT * FROM user WHERE address not like '_中%'

4.view 建立及移除暫存資料表
create view tmp as SELECT * FROM user WHERE address is Null
drop view tmp

5.distinct 重複的不計
SELECT count(distinct address) FROM user WHERE address is Null

【職訓局-手機程式開發班】2013 9/4 Java

1.參照

package test;

class A{
 int aa = 10;
}


class B{
 void c(A a){ // 可以傳類別近來
  a.aa = 3;
 }
}

public class class_text {

 public static void main(String[] args) {
  A a = new A();
  B b = new B();
  
  b.c(a);
  
  System.out.println(a.aa); // a.aa = 3
  
 }

}

2.呼叫自己的function

package test;

public class class_test2 {

 int i;
 
 public static void main(String[] args) {
  
  class_test2 c = new class_test2(); // 自己
  c.i = 10;
  c.A();
  
 }
 
 void A(){
  System.out.println(i);
 }

}
