Use JAVA to print the 9-9 multiplication table with the for statement.

Public class T1 {
Public static void main (String [] args ){
Int k = 1;
For (int I = 1; I <= 9; I ++ ){
System. out. print ("");
While (k <= 9 ){
System. out. print (k + "");
K ++;
}
System. out. println ("");
System. out. print (I + "");
For (int j = 1; j <= I; j ++ ){
System. out. print (I * j + "");
}
System. out. println ("");
}
}
}

Write the 9 × 9 multiplication table of the for statement in C language and rewrite it to the type of the while statement and the do-while statement.

// ============ For form ============
Main ()
{
Int I, j;
For (I = 1; I <= 9; I ++)
{
For (j = 1; j <= I; j ++)
Printf ("% d * % d = % d \ t", j, I, I * j );
Printf ("\ n ");
}
Getch ();
}

// =========== While () form ============================
Main ()
{
Int I, j;
I = 1;
J = 1;
While (I <= 9)

{
While (j <= I)
{
Printf ("% d * % d = % d \ t", j, I, I * j );
J ++;
}
I ++;
Printf ("\ n ");
}
Getch ();
}
