How to remove space after the decimal point without removing other spaces?

I have one String that has multiple values in single string. I just want to remove the space after decimal point only without removing other spaces from string.

String testString = "EB:3668. 19KWh DB:22. 29KWh";

testString = testString.trim();
String beforeDecimal = testString.substring(0, testString.indexOf("."));
String afterDecimal = testString.substring(testString.indexOf("."));

afterDecimal = afterDecimal.replaceAll("\s+", "");

testString = beforeDecimal + afterDecimal;


Here as in my string there is two values in single string EB:3668. 19KWh and DB:22. 29KWh. I just want to remove space after decimal point and make String like this:

EB:3668.19KWh DB:22.29KWh


Just use string.replaceAll("\. ", ".");

Thanks to Henry for pointing out I had to escape the .
