Intro to Java Programming 8 - subString method

In which we discuss one of the methods in the String class in java. We use the substring method to break down a phrase into 2 different parts.

If you have any questions leave a comment below or email me with the subject "java" or "java help".

[narminabdullayeva]

can we use substring with if else statement?Please answer

So when you did the second println statement and did from (5, tutorial.length()) it still includes the last letter? I mean I know it shows the last one, but slightly confused since you said "It includes up to but not including" for the first. Does it just automatically if you do .length for the variable, include the last letter? Thanks

I kinda get it but still get stuck, when using code academy javascript, it asks you to use a substring on "Jan" in January you start from zero so im assuming you stop on n so that would make it (0, 2) but the answer is (0, 3) how is that

How would you do this: Let's say I want to have a user input to a dialog box a filename. Ex: MyJavaProject.java. How do I get the output to be just what is after the dot?

Hi, I am learning Java and i hope you can help with my doubt on how substring() method really works.The print statements below always print a space("") although i thought they would print a part of the original string.

Ex:String s1 ="Java";
System.out.println(s1.substring(1, 1); //was expecting 'a' but prints space
System.out.println(s1.substring(2, 2); //was expecting 'va' but prints space
System.out.println(s1.substring(3, 3); //don't know
System.out.println(s1.substring(4, 4);//don't know
