Numbers and Strings
Java Numbers and Strings
DISCLOSURE:
- Java employs the + operator for concatenation and addition.
- There is an addition of numbers. Concatenated strings are used.
A number is the outcome of adding two numbers:
Example
int x = 10;
int y = 20;
int z = x + y; // z will be 30 (an integer/number)
A string concatenation is produced when two strings are added:
Example
String x = "10";
String y = "20";
String z = x + y; // z will be 1020 (a String)
A string concatenation is what happens when you add a number and a string together:
Example
String x = "10";
int y = 20;
String z = x + y; // z will be 1020 (a String)
