   public static void main(String args[]) {
       //One way of doing concatenation
       String str1 = "Welcome";
       str1 = str1.concat(" to ");
       str1 = str1.concat(" String handling ");
       System.out.println(str1);

       //Other way of doing concatenation in one line
       String str2 = "This";
       str2 = str2.concat(" is").concat(" just a").concat(" String");
       System.out.println(str2);
   }
}

{
	public static void main(String[] args) {
		
		String str1 = "Hello";
		String str2 = "People";
		String str3 = str1 + str2;   // Concatinating two string variables
		
		System.out.println(str3);
		System.out.println(str3 + "!!!");    // Concatinating string variable with a string
	}
}

java string concat

// adding strings with the plus is not elegant use 'String.format()' for it
String s1 = "text1";
String s2 = "text2";
String s3 = "easy: " + s1 + " " + s2;
System.out.println( s3 );
//A "better" way to do this:
String s4 = String.format( "better: %s %s", s1, s2 );
System.out.println( s4 );
// gives:
easy: text1 text2
better: text1 text2

    String second = "Programming";
    System.out.println("Second String: " + second);

    System.out.println("Joined String: " + joinedString);
  }
}

how do you combine 2 strings in java

-By  using (+) operator
-By  using concatenate method (concat()).
                      String strconcat3=strconcat2.concat(strconcat);

-By StringBuffer
-String strconcat= new StringBuilder().append("matt")
                                .append("damon").toString();
                                
-By StringBuilder
- String strconcat2= new StringBuffer()
                  .append("matt").append("damon").toString();
