    private String type;
    // Alternatively you may want a final variable.
    // private final String type;
    
    public DesktopComponent(String type)
    {
        this.type = type;
    }

Answer:
The program to this question can be given as:
Program:
public class Main //define class. 
{ 
public static void main(String[] as) //define main method. 
{ 
 int n=5; //define variable n and assign positive value. 
 int i,j; //define variable 
 for (i = 7; i>=1; i--) //outer loop. 
 { 
 for (j = 0; j< i; j++) //inner loop. 
 { 
 System.out.print("*"); //print asterisks. 
 } 
 System.out.println(); //line break. 
 } 
} 
}
Output:

 Explanation:
The description of the above code can be given as:
- In the above java programming code firstly we define a class that is "Main". In this class we define a main method in the main method we define a variables that is "n" in this variable we assign a positive value. The we define another integer variable that is i,j this variable is used in the loop.
- Then we define a loop. for prints asterisks values in reverse triangle, we nested looping concept. In nested looping, we use in loop in this loop we use the i and j variables that print the asterisks value.
