Java for loops

[stefanmz]

Hey if I have a for loop in java and I want for example

for(int a>=b and int a<=c;a<1000;a++){
...code
}

how do I do that? The a>=b and a<=c part?

All conditional checks go in the second part, where you currently have `a<1000`. First part is for variable initialization.

[RockSolid1106]

First, you initialize your variable, then the condition, followed by what happens to the variable after the loop is executed.

for (int i=0; i<=10; i++){
  //code
}

 

You can also skip certain parts of it by just removing the statement, but leaving the semicolon there.

int i = 5 // already initializing my var

for( ; i<=10; i++){
  // code
 }

oh ok thanks! I got it now!

If you need more complex conditions, you can also use other loop-constructs like while.

int a = …
int b = …
int c = …

while (a >= b && a <= c) {
    … do something
    … do not forget to modify a/b/c
}

oh yeah that actually could be helpful in my case, forgot about that
