Java for loop multiple variables [closed]

Answer 1

Only two Semicolons are allowed to be used in for loop.

1. Before first semicolon is the initialization part.
2. After first semicolon and before second semicolon is condition part (must result in boolean).
3. After second semicolon is variable manipulation part (increment/decrement part).

If you have do initialization of multiple variables or manipulation of multiple variables, you can achieve it by separating them with comma(,).

for(int i=0, j=5; i < 5; i++, j--)

NOTE: Multiple conditions separated by comma are NOT allowed.

for(int i=0, j=5; i < 5, j > 5; i++, j--) // This is NOT allowed.
