Java syntax in Activity

Though Pega suggest us not to use java , certain times we are forced to use java for the complex solutions.
For a guy like me , who did not do java as curriculum always depends on google for the java code.
This post is going to help me to identify the syntax of certain java code which I have used

Use case	Add Log message
Syntax	oLog.infoForced("Log message Here");

Use case	Add try and catch block
Syntax	try { oLog.infoForced("try block executed"); } catch (Exception ex) { oLog.error("catch block executed", ex.toString()); }

Use case	To get current Date and Time
Syntax	Date date1 = java.util.Calendar.getInstance().getTime(); oLog.infoForced("Current Date Time"+ date1);

Use case	To get current Date and Time
Syntax	Date date1 = java.util.Calendar.getInstance().getTime(); oLog.infoForced("Current Date Time"+ date1);

Use case	Convert Bigdecimal(input) to date format
Syntax	DateFormat df = new SimpleDateFormat("dd/MMM/YYYY"); String date = df.format(input); oLog.infoForced("Converted Date format"+ date);

Use case	To create a Clipboard page object from step page/ Page/ datapage
Syntax	ClipboardPage sp1 = myStepPage; ClipboardPage sp2 = tools.getStepPage(); ClipboardPage cp tools.findPage("PageName"); ClipboardPage dp tools.findPage("D_PageName");

Use case	To create a Clipboard property object from step page/ Page/ datapage
Syntax	ClipboardPage cp tools.findPage("PageName"); String ABC = cp.getProperty("pyLabel").toString();

Use case

To Loop over PageList / datapage - (D_PageName.pxResults(1).PNAME)

Syntax

String DatapageName = "D_PageName"; ClipboardPage dpage tools.findPage(DatapageName); if (dpage != null) { ClipboardProperty Results = dpage.getIfPresent("pxResults"); Iterator it = Results.iterator(); while (it.hasNext()) { ClipboardProperty next = (ClipboardProperty) it.next(); ClipboardPage nextPage = next.getPageValue(); ClipbaordProperty propertyname = nextPage.getIfPresent("PNAME"); oLog.infoForced("Print Property"+ propertyname); } }

Use case	For Loop Logic
Syntax	int size = 10000; int size = sp.getProperty("PropertyName").size(); for (int i=1 ; i <= size ; i++) { oLog.infoForced("For logic"+ i); }
