	==Infinite loop:==		==Infinite loop:==
	~~One of the most common mistakes while implementing any sort of looping is that that it may not ever exit~~, ~~that is the loop runs for infinite time~~. ~~This happens when the condition fails for some reason~~.
			Salah satu kesalahan paling umum saat menerapkan segala jenis perulangan adalah bahwa loop tersebut mungkin tidak pernah keluar, yaitu perulangan berjalan untuk waktu yang tak terhingga. Ini terjadi ketika kondisi gagal karena suatu alasan.

	~~Another pitfall is that you might be adding something into you~~ collection ~~object through~~ loop ~~and you can run out of memory~~. ~~If you try and execute the below~~ program, ~~after some time~~, out of memory exception ~~will be thrown~~.		Perangkap lain adalah kita mungkin menambahkan sesuatu ke objek collection kita melalui loop dan kita bisa kehabisan memori. Jika kita mencoba dan menjalankan program di bawah ini, setelah beberapa waktu, out of memory exception akan dikeluarkan.

	~~do-while~~

	do while loop ~~starts with the execution of the statement(s)~~. ~~There is no checking of any condition for the first time~~.		[[File:Loop3.png\|center\|300px\|thumb]]
	~~After the execution of the statements~~, ~~and update of the variable value~~, ~~the condition is checked for~~ true or false ~~value~~. ~~If it is evaluated to~~ true, ~~next iteration of~~ loop ~~starts~~.
			do while loop dimulai dengan menjalankan perintah. Tidak ada pemeriksaan kondisi apa pun untuk pertama kalinya.
			Setelah eksekusi pernyataan, dan pembaruan nilai variabel, kondisi diperiksa untuk nilai true atau false. Jika dievaluasi true, iterasi loop berikutnya dimulai.

			Ketika kondisi menjadi false, loop berakhir yang menandai akhir dari siklus hidup loop.
			Penting untuk dicatat bahwa perulangan do-while akan mengeksekusi pernyataannya setidaknya sekali sebelum kondisi apapun diperiksa, dan oleh karena itu merupakan contoh dari exit control loop.

	~~When the condition becomes false, the loop terminates which marks the end of its life cycle.~~
	~~It is important to note that the do-while loop will execute its statements atleast once before any condition is checked, and therefore is an example of exit control loop.~~

	~~Enhanced For loop~~

	Java ~~also includes another version of~~ for loop ~~introduced in~~ Java 5. Enhanced for loop ~~provides a simpler way to iterate through the elements of a~~ collection or array. ~~It is inflexible and should be used only when there is a need to iterate through the elements in a sequential manner without knowing the index of the currently processed element~~.		===Enhanced For loop===
	~~Also note that the object~~/~~variable is immutable when enhanced for~~ loop ~~is used i.e it ensures that the values in the~~ array ~~can not be modified~~, ~~so it can be said as~~ read-only loop ~~where you can’t update the values as opposite to other loops where values can be modified~~.
	~~We recommend using this form of the~~ for ~~statement instead of the general form whenever possible~~.(~~as per~~ JAVA doc.)		Java juga menyertakan versi lain dari for loop yang diperkenalkan di Java 5. Enhanced for loop menyediakan cara yang lebih sederhana untuk beralih melalui elemen collection atau array. Ini tidak fleksibel dan harus digunakan hanya ketika ada kebutuhan untuk mengulangi elemen secara berurutan tanpa mengetahui indeks elemen yang sedang diproses.

			Perhatikan juga bahwa objek/variabel tidak dapat diubah ketika loop yang ditingkatkan untuk digunakan yaitu memastikan bahwa nilai-nilai dalam array tidak dapat dimodifikasi, sehingga dapat dikatakan sebagai read-only loop di mana kita tidak dapat memperbarui nilai-nilai yang berlawanan dengan loop lain di mana nilai dapat dimodifikasi.

			Sebaiknya gunakan bentuk pernyataan for berikut daripada bentuk umum jika memungkinkan. (sesuai JAVA doc.)

Misalkan ada array nama dan kita ingin mencetak semua nama dalam array tersebut. Mari kita lihat perbedaan antara dua contoh berikut ini.

	While loop ~~starts with the checking of condition~~. ~~If it evaluated to~~ true, ~~then the loop~~ body ~~statements are executed otherwise first statement following the loop is executed~~. ~~For this reason it is also called~~ Entry control loop		While loop dimulai dengan pengecekan kondisi. Jika bernilai true, maka body perintah perulangan akan di jalankan jika tidak, pernyataan pertama setelah perulangan akan di jalankan. Untuk alasan ini juga disebut Entry control loop
	~~Once the condition is evaluated to~~ true, ~~the statements in the~~ loop ~~body are executed~~. ~~Normally the statements contain an~~ update ~~value for the variable being processed for the next iteration~~.
	~~When the condition becomes~~ false, ~~the~~ loop ~~terminates which marks the end of its life cycle~~.		Setelah kondisi dievaluasi ke true, pernyataan di badan loop di jalankan. Biasanya pernyataan berisi nilai yang di update untuk variabel yang sedang diproses untuk iterasi berikutnya.

			Ketika kondisi menjadi false, loop berakhir yang menandai akhir dari siklus loop tersebut.
