Nested Loops: Multiplication Table Generation

Medium

Problem Description

Table Generation with Nested Loops

Outer loop controls rows, inner loop controls columns to generate 2D tables.

Basic Pattern

for (int i = start; i <= end; i++) {     // rows
    For (int j = start; j <= end; j++) { // columns
        System.out.print(i * j);
        If (j < end) System.out.print("\t");
    }
    System.out.println();
}

Learning Points

  • Outer loop: Row control (vertical)
  • Inner loop: Column control (horizontal)
  • Delimiter handling: Add delimiter except for last element
  • println() for newline, print() for continuous output
.
