Types of loop in java

Thanks Sheldon Ron for your answer. But I think

Java has very flexible three looping mechanisms. You can use one of the following three loops:

  • While Loop
  • Do…while Loop
  • For Loop
  • The while Loop:
A while loop is a control structure that allows you to repeat a task a certain number of times.
 
Syntax:
 
The syntax of a while loop is:
 
while(Boolean_expression)
{
   //Statements
}
The do…while Loop:
A do…while loop is similar to a while loop, except that a do…while loop is guaranteed to execute at least one time.
 
Syntax:
 
The syntax of a do…while loop is:
 
do { //Statements }while(Boolean_expression);
 
The for Loop:
 
A for loop is a repetition control structure that allows you to efficiently write a loop that needs to execute a specific number of times.
 
A for loop is useful when you know how many times a task is to be repeated.
 
Syntax:
 
The syntax of a for loop is:
 
for(initialization; Boolean_expression; update)
{
   //Statements
}

Java has four types of loops,

For loop
While Loop
Do While LoopJava has four types of loops,
For loop
While Loop
Do While Loop
For each loop
Syntax:
for ( initializations or statements  separated by comma ; condition evaluates to true or false ; statements separated by comma){
statement or a group of statements;
}
Syntax: 
initializations or statements ;
While (condition evaluates to true or false ){
statement or a group of statements;
}
Syntax: 
initializations or statements ;
Do{
statement or a group of statements;
}While (condition evaluates to true or false )
 
An example of for each loop
int summation(int[] c) {
    int res = 0;
    for (int j : c)
        res += j;
    return res;
}
It prints all the elements of the array ‘c’.
Loops are such control structures that are available in almost all the high-level programming languages.
 
Without this control structure, you may not be able to do almost all tasks. for, while & do While are common to many programming languages. try to develop the logic of loops clearly.
 
Thanks.
