Loops in Java

There are 3 types of Loops in Java

1) while loop

2) for loop

3) do while loop

4) for each loop


u can use any loop as per your convenience 


while >>>>>>>>>>>>>>>

int i = 1;   

while (i<= 10){

i++; }

System.out.print("finish my loop");


Yaha int i = 1 ka mtlb hai initialize mtlb ham start kaha se kr rhe yaha main 1 se start kr rha

matlb maine kaha i nam ka integer bna lo jiski value store kr do 1 se

aur tb tk run kro jab tk i 10 se chota na ho aur 10 ke barabar na ho 

maine 1 bar chalaya lekin normal program ki trh increment nhi hoga , aage nhi bdhega

to hamne yaha i++ kiya mtlb 1 aage bdhaya, increment kiya aur phir se ye check karega i hamara 2 tha to kya i 10 se chota hai to yeh 3 bna dega  


mtlb jab tk loop khtm nhi hota tb tk loop ke bahar ka print nhi hoga ,



infinite loop kaise lgate hai .  . . . . . . . 


while(true)

System.out.print("");


jab tk condition false nhi ho jata tb tk while  loop run hota rhta hai




do while >>>>>>>>>

package CoreJava;

import java.util.Scanner;

import java.util.Random;

public class javaCore {

public static void main (String [] args) {

Scanner scan = new Scanner(System.in);

Random random = new Random();

int a = 0;

do {

System.out.println(a);

a++;

}while(a<5);



}

}

yaha kya ho rha do while me condition check kiye bina hi loop me ghus jata hai.



for each  ---------------
for each loop is basically introduced in new version of java 

Example - - -

int [] avg = {120, 223, 42, 543};

// System.out.println(avg.length);

for (int element: avg) {

System.out.println(element);

}
