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

Balaji R | 03/10/2016

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