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); } |
