String Concatenation:

String concatenation is the process of combining two or more strings to form a single string. In Java, we can use the "+" operator to concatenate two or more strings.

Example:

String str1 = "Hello";
String str2 = "World";
String result = str1 + str2;
System.out.println(result); // Output: HelloWorld

String Length:

The length() method in Java returns the length of the string. It returns the number of characters present in the string, including white spaces.

Example:

String str = "Hello World";
int len = str.length();
System.out.println(len); 

Output for the above program is as follows
