Question

int a=25: 
for (double i=1;i<=a;i++) 
{
    int b=5*i; 
    boolean value= b==a; 
    System.out.println(value);
 }

This method is true when i=5 but false otherwise. So the value can be true at i=5 but my program will print for me : false-false-false-false-TRUE-false-false-false… how can I make this program to print just TRUE for me. PS: I know that false or false or TRUE or false = True.. but how can I use it in the for loop?

Answer 1

Maybe this?

int a=25; 
for (double i=1;i<=a;i++) { 
    int b = 5 * (int)i;  // you must cast "i" in order for this to compile 
    boolean value = b == a;  // you probably wanted "b == a" not "b == i" 
    if (value)
        System.out.println("true");
}

i.e. we print "true" only if value is true.

To stop the loop when value becomes true, we can use a break statement:

int a=25; 
for (double i=1;i<=a;i++) { 
    int b = 5 * (int)i;
    boolean value = b == a; 
    if (value) {
        System.out.println("true");
        break;
    }
}
