I have a string where I want to replace all of the spaces with plus (+) symbols.
I've tried a number of different ways but the debug log is always showing that nothing is being replaced
I'm passing in a = 101 e wilson st c = madison z = 53703
the end result should be: 101+e+wilson+st+madison+53703
However it's coming out as: 101 e wilson st+madison+53703
string param = a + '+' + c + '+' + z;
So the replace all Regex is not working.
Apex:
public void getCoord(string a, string c, string z){
Http h = new Http();
HttpRequest req = new HttpRequest();
a.replaceAll('\\s+', '-');
c.replaceAll('\\s+', '-');
z.replaceAll('\\s+', '-');
string param = a + '+' + c + '+' + z;
system.debug('looking for coordinates');
req.setEndpoint('https://maps.googleapis.com/maps/api/geocode/json?address='+ param +'&sensor=false');

The replaceAll method returns the modified string, it does not modify the reference to the value passed.
So you should change it to this and it should work for you:
