Learning programming is more than learning a language. Let me divide your effort into few chunks -- Learning the fundamentals/theory of programming; This might take anywhere from one months to at least 6 month (1 semester in a university undergrad course) Learning the art of developing algorithm; This part is very squiggly and ill defined. People spend most of their professional carrier learning this. Learning the syntax of the programming language; this is the recurring part that you have to do while learning multiple languages. The concepts remain same; only the language syntax changes. For a person well conversant in the above 2, mere learning this would be a piece of cake. I would say 2 weeks. For you particular ( a person with no prior programming experience), I will expect about 9 (5+3+1)months to completely understand and write Java programs.

Hi Ruchi, Answering your queries in the same sequence - 1- Basic need of Java for quick learning and understanding is Knowledge of basic programming like C/C++. It doesn't mean if you can't learn it. Still you can but it will take a bit more time to get the basic understanding of Java. 2- For Core Java it will take 6-8 months to get complete practical or professional knowledge of Java.

I have done this in javascript . i think u just only need to replace the var with string . var myStr = "Thith ith my thtring"; var newStr = ""; for(var i=0;i


Abhishek Kumar | 08/09/2016

Apart from all the basic ways, this can be done with the help of pattern(regular expressions) which in-turn applies String class replaceAll method: public static String replaceString(String sourceStr, String replaceString, String replaceBy) { return Pattern.compile(replaceString).matcher(sourceStr).replaceAll(replaceBy); } public static void main(String[] args) { System.out.println(replaceString("This is my string", "s", "th")); } Output: Thith ith my thtring

If your question is how to program in java, then you can do that by downloading jdk on your system. Then you can either work from command line and compile and run your programs manually with javac and java commands. Or you can download an IDE like eclipse or netbeans which automatically detects java installation on your system and provide you an easy interface to work with. Happy coding. Thanx

Deb Prakash Chatterjee | 06/09/2016

You Have to write code in IDE and make many more exciting programs. That's how java is used.

Syntactically yes.. you can create object by inner anonymous class. But that is not creating any object in heap as other normal concrete class. so basic answer is no.


Balaji R | 03/10/2016

No. 'Abstract' means incomplete. Abstract class is also an incomplete class. Only concrete classes can be instantiated.
