Removes spaces and words that begin with a specific character from a Java string

Remove spaces and words beginning with specific characters from Java strings

Code spaces are eliminated by the following code areas:

String str1= "This is symbel for sNow and silk. Grapes are very dear"
String str2=str1.replaceAll(" ","");
System.out.println(str2);

It gives this output: –

output:
ThisissymbelforsNowandsilk.Grapesareverydear

But I want to eliminate all the words in STR1, start with char's' (symbol snow silk) and char'd '(Dear), and get the following output: –

output:
Thisisforand.Grapesarevery

How to modify this code?

Solution

Do it in this way.

String str1= "This is symbel for sNow and silk. Grapes are very dear";
System.out.print(str1.replaceAll("[sd][a-z]+|[ ]+",""));
