In Java, you can use the concatenation operator (+) to add a space between two strings.
For example:
String str1 = "Hello";
String str2 = "World";
String str3 = str1 + " " + str2;
System.out.println(str3);
This will output the string "Hello World".
Alternatively, you can use the String.format() method with placeholders and the %s flag to insert the strings and a space between them:,
String str1 = "Hello";
String str2 = "World";
String str3 = String.format("%s %s", str1, str2);
System.out.println(str3);
This will also output the string "Hello World".
Another way is to use join method of String class like this
String str1 = "Hello";
String str2 = "World";
String str3 = String.join(" ", str1, str2);
System.out.println(str3);
In all the above examples, the space between the two strings is represented by a single space character within the quotation marks. You can also use multiple space characters or any other characters if you like.

Frequently Asked Questions About The Error
What does the error message say?
The error message will typically indicate what type of error has occurred and where it occurred in the code. This information can be used to troubleshoot and fix the issue.
Are there any syntax errors?
Syntax errors occur when the code does not conform to the rules of the programming language. These errors can include missing semicolons, misused keywords, and incorrect use of operators.
Are there any logical errors?
Logical errors occur when the code is syntactically correct but does not perform the intended action. These errors can be caused by incorrect use of variables, logic or method calls.
Are there any missing or incorrect dependencies?
Missing or incorrect dependencies can cause errors. These errors can occur when the code relies on a library or framework that is not properly included or configured in the project.
Are there any missing or incorrect values in the code?
Missing or incorrect values can cause errors. These errors can occur when the code relies on certain variables or parameters that have not been properly set or passed in.
Are there any discrepancies between the runtime and development environment?
Errors can occur when the code is run in a different environment than it was developed in. This can happen when there are differences in the version of a library or framework, or when the code is run on a different operating system.
