Hi All, I’m still finding nested loops a little confusing and I have been told that the following code prints 10 when compiled and run but I can’t figure out why! I’m getting 3 so obviously going wrong somewhere, is anyone able to explain this to me please? class Test{ public st...
Java For LoopWhen you know exactly how many times you want to loop through a block of code, use the for loop instead of a while loop:SyntaxGet your own Java Server for (statement 1; statement 2; statement 3) { // code block to be executed }...
Nested LoopsIt is possible to place a loop inside another loop.Here, the "inner loop" will be executed one time for each iteration of the "outer loop":Example package main import ("fmt") func main() { adj := [2]string{"big", "tasty"} fruits := [3]string{"apple", "orange", ...
Infinite loops and break statements Another loop pattern you can write in Go is the infinite loop. In this case, you don't write a condition expression or a prestatement or poststatement. Instead, you write your way out of the loop. Otherwise, the logic will never exit. To make the log...
// No longer the preferred idiom to iterate over an array! for (int i = 0; i < a.length; i++) { doSomething(a[i]); } //The preferred idiom for iterating over collections and arrays for (Element e : elements) { doSomething(e); ...
so it can be used in the termination and increment expressions as well. If the variable that controls aforstatement is not needed outside of the loop, it's best to declare the variable in the initialization expression. The namesi,j, andkare often used to controlforloops; declaring them wi...

When a method is first compiled by C1 some basic information is collected about its structure, like the number of instructions and loops. Based on that information it can be decided that a method is trivial – it returns a constant or is a getter or setter (see source here)– and compili...
[18] refactor Java code to use λ-expressions instead of imperative-style loops. Tsantalis et al. [83] transform clones to λ-expressions. Khatchadourian and Masuhara [84] refactor skeletal implementations to default methods. Tip et al. [85] use type constraints to refactor class hierarchies...
the for-each loop is not usable for filtering. Similarly it is not usable for loops where you need to replace elements in a list or array as you traverse it. Finally, it is not usable for loops that must iterate over multiple collections in parallel. These shortcomings were known by the...
