I would like to generate sequence number from 01 to 10. But I only want the odd ones. For example,
01 03 05 07 09
I tried this way.
for (int i = 1; i < 10; i++) { String sequence = String.format("%02d", i); System.out.println(sequence); //this prints out from 01,02,03.... to 09. So how should I change my code to omit the even ones in between?
Since you want it formatted, only with odd numbers, this outputs:
01 03 05 07 09
for (int i = 1; i < 10; i+=2) System.out.println( String.format("%02d", i) ); Use a for loop changing the increment stage:
for (int i = 1; i < 10; i += 2) System.out.println(i); You can just make the loop increment by 2 instead of by just 1!
Example with your code:
for (int i = 1; i < 10; i+=2) { String sequence = String.format("%02d", i); System.out.println(sequence); } just use a loop
For loop
for(int i=1;i<=10;i+=2) System.out.println(i); While loop
int i=1; while(i<=10){ System.out.println(i); i+=2; } Do-While loop
int i=1; do{ System.out.println(i); i+=2}while(i<=10); 
i += 2in the loop?if(i%2==1)(the modulo operator)
