Parameter Passing

ภาษา Java มีข้อกำหนดที่แตกต่างจากภาษาอื่นคือ

  • ถ้า arguments ใดเป็นชนิดข้อมูลพื้นฐานจะถูกส่งค่าแบบ pass by value
  • ถ้า arguments ใด้เป็น instances ของคลาสใดๆ จะถูกส่งค่าแบบ pass by reference

Primitive Type

ภาษา Java มีชนิดข้อมูลพื้นฐานที่มีมากับภาษา 8 ชนิด แบ่งเป็น 4 กลุ่มได้ดังนี้

  1. Truth Value คือ boolean(1bit) มีค่าเป็น true หรือ false เท่านั้น
  2. Integer คือ byte, short, int, long ตัวแปรของชนิดข้อมูลเหล่านี้สามารถเก็บค่าที่เป็นบวกหรือลบได้
  • byte(8 bits)  max = 127, min = -128
  • short(16 bits) max = 32767, min = -32768
  •  int(32 bits) max = 2147483647, min = -2147483648
  • long(64 bits) max = 9223372036854775807, min = -9223372036854775808
     3.  Real Number มีสองประเภทคือ float และ double
  • float(32 bits) max = 3.4028235E38, min = 1.4E-45
  • double(64 bits) max = 1.7976931348623157E308, min = 4.9-324
    4.  Character คือ ชนิดข้อมูล char สำหรับเก็บตัวอักษร Unicode ใช้หน่วยความจำ 16 bits ต่อตัว

พิสูจน์ Normal Form (3NF)

พิสูจน์ Normal Form (3NF)


  1. ไม่มี Repeating groups (1NF)
  • จะต้องไม่มีข้อมูลในคอลัมน์ใดที่มีข้อมูลมากกว่า 1 ค่า
     2.  ไม่เกิด Partial Dependency

  • เป็น 1NF และทุกคอลัมน์ที่ไม่ใช่คีย์จะต้องขึ้นกับ Primary key โดยสมบูรณ์แม้ว่า Primary key จะ

    เป็น composition key ก็ตาม
     3.  ไม่เกิด Transitive Dependency
  • เป็น 2NF และต้องไม่มีคอลัมน์ใดขึ้นต่อคอลัมน์อื่นที่ไม่ใช้ Primary key

There are different distribution packages for various JRE versions and hardware processors available:

sapjco-ntintel-2.1.9.zip for a 32-bit JRE running on a 32-bit INTEL x86 or a 64-bit INTEL Itanium processor
sapjco-ntia64-2.1.9.zip for a 64-bit JRE running on a 64-bit INTEL Itanium processor
sapjco-ntamd64-2.1.9.tgz for a 64-bit JRE running on a 64-bit AMD or INTEL x86 processor
To install JCo for Windows unzip the appropriate distribution package into an arbitrary directory {sapjco-install-path}.
If you already have an older librfc32.dll in the {windows-dir}\system32 directory, please replace it with the one that comes with JCo.
Then add {sapjco-install-path} to the PATH environment variable.
Finally, add {sapjco-install-path}\sapjco.jar to your CLASSPATH environment variable.

ให้ keyboard กดแป้น enter หรือ space ได้

$("#empId").keypress(function(event) {
            if (event.which === 13) {//Enter
                $('#btnSearch').focus().click();
            }
            if (event.which === 32) {//Space
                $('#btnPay').focus().click();
            }
});

เปลี่ยนเป็นอักษรตัวใหญ่

onKeyUp="this.value = this.value.toUpperCase()"

รับค่าตัวเลขเท่านั้น

function checkNumber()
{
        key = event.keyCode
                if (key < 48 || key > 57)
                event.returnValue = false;
}
