List of Code Snippets/Templates to Eclipse IDE Tricks



You can add Code Snippets/Templates to your program in Eclipse IDE by typing the snippet keyword and pressing Ctrl + Space keys. Using them you can code faster as you do not need to type much.

Lets see the most commonly used code statement example System.out.println(), to get this line of code, simply type sysout and press control + space

To see what snippets are available you can type a word say f and press ctrl+space twice and choose form the options available.

List of Code Snippets/Templates




    Below is a list of some 27 code Snippets that are available in java programming with Eclipse.
//1. for : iterate over array
for (int i = 0; i < args.length; i++) {
	
}




//2. for iterate over array with temp varaible 
for (int i = 0; i < args.length; i++) {
	String string = args[i];
	
}





//3. for  over collection 
for (Iterator iterator = collection.iterator(); iterator.hasNext();) {
	type type = (type) iterator.next();
	
}




//4. foreach : iterate over an array or iterable 
for (String string : args) {
	
}



	
//5. arrayadd : add an element to an array
String[] args2 = new String[args.length + 1];
System.arraycopy(args, 0, args2, 0, args.length);
args2[args.length] = f;





//6. arraymerge : marge two array into one
String[] args3 = new String[args.length + args2.length];
System.arraycopy(args, 0, args3, 0, args.length);
System.arraycopy(args2, 0, args3, args.length, args2.length);





//7. cast : typecast template
type new_name = (type) name;




//8. catch : add a catch block
catch (Exception e) {
	// TODO: handle exception
}




//9. do : do-while loop
do {
	
} while (condition);




//10. else : else block
else {
	
}




//11. elseif : else if block
else if (condition) {
	
}



   
//12 : if : if condition
if (condition) {
	
}




//13. ifelse : if else stataement 
if (condition) {
	
} else {

}


	
//14. insteadof : dymanic type test and cast
if (args3 instanceof type) {
	type new_name = (type) args3;
	
}




//15.lazy : lazy creation
	
if (args3 == null) {
	args3 = new type(arguments);
	
}

return args3;





//16. new : create new object
type name = new type(arguments);
	
//17. runnable : 
new Runnable() {
	public void run() {

	}
	

}






//18. Switch : swich case
switch (key) {
case value:
	
	break;

default:
	break;
}




//19 : synchronized : synchronized block
synchronized (args3) {
	
}





//20. syserr : system error : System.err.println()
System.err.println();






//21. sysout : print a statement out System.out.prinlt.ln
System.out.println();





//22. systrace : Print the current method to standard output
	    System.out.println("Example.main()");
	    
	    
	    //23. try : try block
	    try {
	
} catch (Exception e) {
	// TODO: handle exception
}
	
	    
	    
	    
	   
//24. toarray : convert collection to array.
	    
	    (type[]) collection.toArray(new type[collection.size()])

	    
	    
	    
//25.while : iterate with enumeration
	    while (en.hasMoreElements()) {
	type type = (type) en.nextElement();
	
}
	    
	    
	    
	    
//26.while : iterate with iterator
	    while (it.hasNext()) {
	type type = (type) it.next();
	
}
	
	    
	    
//27. While loop with condition
	    while (condition) {
	
}
