Java break statement is a branching statement in a control flow statement and it will terminate the iteration of a loop even though the looping expression is valid (i.e., true). There are two types of Break Statement.
The break statement is a termination statement and its used to terminate the innermost while, do-while, for, or switch statement even though the expression is valid (i.e. true).
The Labeled break statement is a termination statement and it's used to terminate the outermost while, do-while, for, or switch statement even though the expression is valid (i.e. true). Moreover the labeled break statement will be used commonly in the nested loops to break the outermost loop.
Find the value 4 in 1-dimensional array and terminate the loop using simple break statement only if the value exist.
