Concat is short for concatenation, which means to join two strings together
public void concatMethod1()
{
String str1;
String str2;
String str;
// set up the values of the two strings to join together
str1 = "Joe";
str2 = "Student";
// join the two strings together
str1 = str1.concat(" "); // why is this line needed?
str = str1.concat(str2);
// This will also work, but may not be as clear
// str = str1.concat(" ").concat(str2);
// output the new string
System.out.println(str);
}
public void concatMethod2()
{
String str1;
String str2;
String str;
// set up the values of the two strings to join together
str1 = "Joe";
str2 = "Student";
// join the two strings together
str = str1 + " " + str2;
// output the new string
System.out.println(str);
