Java Right-Angled Triangle: Print with Nested Loops

Nested loops can be used to print a right-angled triangle as shown below:

public class PrintTriangle {
    public static void main(String[] args) {
        int rows = 5; // 三角形的行数
        
        for (int i = 1; i <= rows; i++) {
            for (int j = 1; j <= i; j++) {
                System.out.print("* ");
            }
            System.out.println();
        }
    }
}

Running the above code will output:

* 
* * 
* * * 
* * * * 
* * * * * 

You can adjust the value of rows as needed to control the size of the triangle.
