How can you combine two sentences into one?

Question:
How do you append a string with another string?

Code:
public class AppendString {
   public static void main(String[] args) {
 
      String str1 = "I like java";
      String str2 = "I like pizza";
 
      System.out.println("str1: " + str1);
      System.out.println("str2: " + str2);
 
      String str3 = str1 + " and " + str2;
      System.out.println("str3: " + str3);
   }
}

Output:
$ java AppendString 
str1: I like java
str2: I like pizza
str3: I like java and I like pizza
