    *****
    *****

Solution:

public class Main{
    public static void main(String[] args) {
        Patterns(5);
    }

    public static void Patterns(int n){
  //run the outer loop same as the number of rows
  for(int i = 0; i < n; i++){

//run the inner loop same as the number of columns
    for(int j = 0; j < n; j++){
        System.out.print("* ");
    }
    System.out.println();
  }
   
    }
}

QUESTION2:

SOLUTION:

public class Hello{
    public static void main(String[] args) {
        Patterns(5);
    }

public static void Patterns(int n){
    //run the outer loop same as the number of rows
  for(int i = 0; i < n; i++){

//run the inner loop same as the number of columns
    for(int j = 0; j <= i; j++){
        System.out.print("* ");
    }
    System.out.println();
  }
   
}
}

QUESTION3:

SOLUTION:

public class Hello{
    public static void main(String[] args) {
        Patterns(5);
    }

public static void Patterns(int n){
    //run the outer loop same as the number of rows
  for(int i = n; i > 0; i--){
    for(int j = 1; j <= i; j++){
        System.out.print("* ");
    }
    System.out.println();
  }
   
}
}

QUESTION4:

4.  1
    1 2
    1 2 3
    1 2 3 4
    1 2 3 4 5

SOLUTION:

public class Hello{
    public static void main(String[] args) {
        Patterns(5);
    }

public static void Patterns(int n){
    //run the outer loop same as the number of rows
//As we are going to print numbers so start the loop with 1 not with 0
//anotherwise, it'll look messy

  for(int i = 1; i <= n; i++){
    for(int j = 1; j <= i; j++){
        System.out.print(j + " ");
    }
    System.out.println();
  }
   
}
}

QUESTION5:

SOLUTION:

public class Hello{
    public static void main(String[] args) {
        Patterns(5);
    }

public static void Patterns(int n){
  //run the outer loop same as the number of rows
  for(int i = 1; i < 2*n; i++){

//Everything will remain same but the main thing to define is this c
//which will tell how manu columns are going to be printed as the loop runs
    int c = i > n ? 2*n - i : i;

    for(int j = 1; j <= c; j++){
        System.out.print("* ");
    }
    System.out.println();
  }
   
}
}
