---------------------------------------
**Pattern A**
**Pattern B**
---------------------------------------
- Pattern A displays an increasing number of plus signs (`+`) aligned to the left. The sequence is as follows:
- Row 1: `+`
- Row 2: `++`
- Row 3: `+++`
- Row 4: `++++`
- Row 5: `+++++`
- Pattern B exhibits a decreasing number of plus signs (`+`) aligned to the right. The sequence is as follows:
- Row 1: `+++++`
- Row 2: `++++`
- Row 3: `+++`
- Row 4: `++`
- Row 5: `+`
Expert Solution

Step 1
For pattern A the code is given below:
import java.util.Scanner;
public class Main
{
public static void main(String[] args) {
Scanner sc=new Scanner(System.in);
System.out.println("How many rows would you like to print");// asking for input
int n=sc.nextInt();// storing the input
System.out.println("Patter A");
System.out.println();// for next line
for(int i=0;i<n;i++){
for(int j=0;j<=i;j++){
System.out.print("+");// printing the pattern
}
System.out.println();// for next line
}
}
}
For pattern B the code is given below:
import java.util.Scanner;
public class Main
{
public static void main(String[] args) {
Scanner sc=new Scanner(System.in);
System.out.println("How many rows would you like to print");// asking for input
int n=sc.nextInt();// storing the input
System.out.println("Patter B");
System.out.println();// for next line
for(int i=0;i<n;i++){
for(int j=n;j>i;j--){
System.out.print("+");// printing the pattern
}
System.out.println();// for next line
}
}
}
