What is String concatenation in java?

You can use + operator to concatenate two Strings.

Eg. String firstName=”Jenny ”;

String lastName= “Peter”;

When we want to get the full name of the person, we can concatenate two Strings firstName and lastName and get the fullName.

fullName=fisrtName+lastName;

or

fullName=”Jenny “+lastName;

When you concatenate a string with another value, that value is converted to String.

Eg. int age=25;

String output =age+” years”;

Now output is “42 years”
