Java Loop statements
Whenever nosotros desire to execute a block of statements several times together with then nosotros role Loop structures.
There are 4 types of loop construction inwards Java.
1) for Loop
2) spell Loop
3) do...while Loop
4) Enhanced for Loop
-------------------------
1) for Loop
It repeats a block of statements for a specified discover of times.
Syntax:
for(stratvalue; endValue; increment/decrement) {
Statements
---------
--------
}
Example:
for (int i=1; i<=10; i++)
{
System.out.println(i);
}
Example 2:
// impress ten to i Numbers using For Loop.
for (int i=10; i>=1; i--)
{
System.out.println(i);
}
Example 3:// impress every tenth Number upwardly to 100.
for (int i=10; i<=100; i=i+10)
{
System.out.println(i);
}
--------------------------------------
2) spell Loop
It repeats a block of statements spell status is true.
Syntax:
Initialization
while (condition) {
statements
------
-------
increment/decrement
}
Example:// impress i to ten Numbers using While Loop.
int i = 1;
spell (i <=10){
System.out.println(i);
i++;
}
Example 2:// impress ten to i Numbers using While Loop.
int i = 10;
spell (i >= 1){
System.out.println(i);
i--;
}
Example 3:// impress every tenth discover upwardly to 100 using While Loop.
int i = 10;
spell (i <= 100){
System.out.println(i);
i= i+10;
}
--------------------------------------
3) produce ...while Loop---------------------------------------
it repeats a block of statements spell status is truthful together with Irrespective of the condition, it executes a block of statements at to the lowest degree once.
Syntax:
do
{
Statements
----------
----------
Increment/Decrement
} while(Condition);
------------
Example:int i = 20;
produce {
System.out.println("i value is : " + i);
i++;
} while(i <= 10);
---------------------------------------
4) Enhanced for Loop---------------------------------------
It executes all elements inwards an Array
Syntax:
for (declaration: expression) {
statements
----------
-----------
}
Example:String languages [] = {"C", "C++", "Java", "COBOL"};
for (String lang: languages)
{
System.out.println(lang);
}
