Java String: concat()

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);
