In Java, we have two types of comments. We use comments to write some text within our code. The compiler will ignore these comments.
Syntax:
|
1
|
// Single line comment
|
|
1
2
3
|
/* Multi line comments – Line 1
Multi line comments – Line 2
*/
|
Note: Comments in between the code gives more readability
Do you want to show auto-generated code whenever you create a new class as shown below?
Follow the below steps:
I assume you are using Eclipse IDE.
1. In eclipse, Go to Window – Preferences
2. From the left panel, Select Java – Code style – Code template
3. Under ‘Configure generated code and comments’, Expand Comments – Select Files and Click Edit and Enter your text and click OK.
Whenever you create a new class, you can see comments.

package classOneGeneral;
public class Comments {
public static void main(String [] args){
// Single line comment – Below statement outputs the string “I am learning Java from SoftwareTestingMaterial”
System.out.println(“I am learning Java from SoftwareTestingMaterial”);
/* Multi line comments – Below statement outputs the string
Multi line comments – “I am learning Java from SoftwareTestingMaterial”
*/
System.out.println(“I am learning Java from SoftwareTestingMaterial”);
}
}
