String stringVar = '';

Hi,

Below is the sample code.I would suggest you refer below document to know all the methods with String class in salesforce.

https://developer.salesforce.com/docs/atlas.en-us.apexcode.meta/apexcode/apex_methods_system_string.htm 
String empty = '';
String nullString = null;
System.assert(String.isEmpty(empty));
System.assert(String.isEmpty(nullString));
String whitespace = '  ';
String alpha = 'Hello';
System.assert(!String.isEmpty(whitespace));
System.assert(!String.isEmpty(alpha));

Please mark it as solved if my reply was helpful, it will make it available
for others as a proper solution.

Best Regards,
​Sandhya
