Giving multiple conditions in for loop in Java [closed]

Answer 1

It is possible to use multiple variables and conditions in a for loop like in the example given below.

 for (int i = 1, j = 100; i <= 100 && j > 0; i = i - 1 , j = j-1) {
     System.out.println("Inside For Loop");
 }

Answer 2

You can also use "or" operator,

for( int i = 0 ; i < 100 || someOtherCondition() ; i++ ) {
  ...
}

Answer 3

If you prefer a code with a pretty look, you can do a break:

for(int j = 0; ; j++){
    if(j < 6
    && j < ( (int) abc[j] & 0xff)){
        break;
    }

    // Put your code here
}

Answer 4

A basic for statement includes

• 0..n initialization statements (ForInit)
• 0..1 expression statements that evaluate to boolean or Boolean (ForStatement) and
• 0..n update statements (ForUpdate)

If you need multiple conditions to build your ForStatement, then use the standard logic operators (&&, ||, |, ...) but - I suggest to use a private method if it gets to complicated:

for (int i = 0, j = 0; isMatrixElement(i,j,myArray); i++, j++) { 
   // ...
}

and

private boolean isMatrixElement(i,j,myArray) {
  return (i < myArray.length) && (j < myArray[i].length);  //  stupid dummy code!
}

Answer 5

If you want to do that why not go with a while, for ease of mind? :P No, but seriously I didn't know that and seems kinda nice so thanks, nice to know!

Answer 6

You can also replace complicated condition with single method call to make it less evil in maintain.
