Program the first 10 odd number

Answer 1

Question:-

• Program the first 10 odd numbers
• Java

Answer:-

1st Approach:-

//Java program to print the first 10 odd numbers

package Programmer ; // Optional statement, no need to write this Statement

public class OddPrint {

public static void main (String ar []) {

int a=1;

for (int I=1;I<=10;I++,a+=2)

System.out.println(a);

}

}

2nd Approach(Shortest):-

//Java program to print first 10 odd numbers

package Programmer; // Optional statement, no need to write this Statement

public class OddPrint {

public static void main (String ar []){

for(int I=1;I<=20;I+=2){

System.out.println(I);

}

}

}

Explaination of Approach 1:-

• a is intialized to 1
• The program runs a loop from 1 to 10
• a is printed
• Next loop.. I get updated with +1 and at the same time a is updated with +2
• When I becomes 11, loop terminates and hence the program ends

Explaination of Approach 2:-

• There is no difference in working but the only difference is that in this case the loop runs from 1 to 20 and is printed directly followed by updation with +2.
• When I is 21, loop terminates and hence the program ends.
