用java打印一个九九乘法表

Sure, here's the Java code to print a multiplication table:

public class MultiplicationTable {
    public static void main(String[] args) {
        int n = 9;
        for (int i = 1; i <= n; i++) {
            for (int j = 1; j <= i; j++) {
                System.out.print(j + " x " + i + " = " + (i*j) + "\t");
            }
            System.out.println();
        }
    }
}

This will print out the multiplication table from 1x1 to 9x9.
