The simple program which check a year either leap year or normal year.

    public static void main(String[] args) { 
        int year = Integer.parseInt(args[0]);
        boolean isLeapYear;

        // divisible by 4
        isLeapYear = (year % 4 == 0);

        // divisible by 4 and not 100
        isLeapYear = isLeapYear && (year % 100 != 0);

        // divisible by 4 and not 100 unless divisible by 400
        isLeapYear = isLeapYear || (year % 400 == 0);

        System.out.println(isLeapYear);

In this entry I would like to introduce some basic usage of mig layout.

This is image I take in eclipse, we can use window builder plug-in for drag-draw UI.

Code	Detail	Description
Contructor of MigLayout: new MigLayout("insets 50 50 0 50", "[74.00]20[165.00][grow]", "[][][]")	-    "insets 50 50 0 50"	-    Decribe margin. insets top left bottom right
	-    "[74.00]20[165.00][grow]"	-    Number of columns + [74.00]: size of column 1 is 74px. + [74.00]20[165.00]: gap between 1st colum and 2nd is 20px. [grow]: 3rd column is grow
	-    "[][][]"	-    Number of rows.
JLabel lblNewLabel = new JLabel("Label 1");             panel.add(lblNewLabel, "cell 0 0,alignx leading");	-    "cell 0 0,alignx leading"	-    “Label 1” is put to column 0 and row 0. It’saligned from left to right
JLabel lblNewLabel_2 = new JLabel("Label 3");             panel.add(lblNewLabel_2,"cell 0 2,alignx trailing");	-    "cell 0 2,alignx trailing"	-    “Label 1” is aligned from right to left.
textField = newJTextField();             panel.add(textField, "cell 1 0");	-    "cell 1 0"	-    textField is put to 1st column and row 0.
textField_1 = newJTextField();             panel.add(textField_1, "cell   1 1,growx");	-    "cell 1 1,growx"	-    textField_1 is put to 1st column and 1 row. -    Growx: witdh of this text field is always equal with width of column.
textField_2 = newJTextField();             panel.add(textField_2, "cell   1 2,growx,span");	-    "cell 1 2,growx,span"	-    Span: this text field is put to columns, 1st column is 1 (cell 1 2) and others are rest of columns in layout. -    “span colums rows”
