1.Print all numbers from 1 to 100
class Main {
public static void main(String[] args) {
for(int i=1;i<=100;i++){
System.out.print(i+” “);
2.Print alternatative numbers from 1 to 100(1,3,5,7…)
class Main {
public static void main(String[] args) {
for(int i=1;i<=100;i++){
System.out.print(i+" ");
i=i+1;
3. Print alternatative numbers from 1 to 100(0,2,4…)
class Main {
public static void main(String[] args) {
for(int i=0;i<=100;i++){
System.out.print(i+" ");
i=i+1;
}
4.print all number in reverse order from 100 to 0
class Main {
public static void main(String[] args) {
for(int i=100;i>=0;i--){
System.out.print(i+" ");
// i=i+1;
5.print all number from 100 to 0 by skipping 2
class Main {
