Loops in any programming language are used to execute or run a set of instructions also called functions continually until the conditions become true.
In the Java programming language, basically, four types of loops:
- For Loops
- For-Each Loops
- While Loops
- Do-While Loops
1.For Loops:
public class Loops {
public static void main(String[] args){
// here first I will declare an array like
int[] array = {1,2,3,4,5,6,7,8};
for(int i =0; i<8; i++){
System.out.println(array[i]);
}
}
}
2.For-Each Loops
public class Loops {
public static void main(String[] args){
// here first I will declare an array like
int[] array = {1,2,3,4,5,6,7,8};
for(int i :array){
System.out.println(i);
}
}
}
To Know the Functionality of the Loops, Just watch the video, where you can find the step to step-wise tutorials on Loops Operations in Java:
3. While Loops:
public class Loops {
public static void main(String[] args){
// here first I will declare an array like
int[] array = {1,2,3,4,5,6,7,8};
int i =0;
while(i<array.length){
System.out.println(array[i]);
i++;
}
}
}
4. Do-While Loops:
public class Loops {
public static void main(String[] args){
// here first I will declare an array like
int[] array = {1,2,3,4,5,6,7,8};
int i =0;
do{
System.out.println(array[i]);
i++;
}
while(i<array.length){
}
}
}
