Is there an easy way to convert a simple integer into a boolean type?

## All 8 Replies

`(i != 0)`

use:

``````boolean b;
int iSomeValue;

b=true;
if(iSomeValue==0)b=false;``````

or use function

``````boolean intToBool(int iVal)
{
boolean b=true;
if(iVal==0)b=false;
return b;
}``````

That is a lot more code than is needed. The conversion only needs the evaluation of intVal!=0, so the function reduces to

``````boolean intToBool(int value){
return (value != 0);
}``````

Thanks for the help, by th way i used ezzral's method it was quick and simple, i also found out i could've just started with a boolean by setting random generator class to boolean type.

Use

``int intVal = (boolVal) ? 1 : 0;``

Why do you want to convert a boolean to an int.

It makes no sense. A boolean has 2 values, an int has billions.
Why would one of the billion values be true and another be false?
0 and NOT 0 are C concepts. Nothing in java corresponds.

This thread has been solved but I would also like to add a small suggestion. If for some reason you want to use ints for boolean expressions, why don't you make a class for it. Call it: BoolInt. Have it have one int private attribute and with the help of public set methods make sure that the only valid values are 1 and 0 (or whatever you want)

``````class BoolInt {
public static final int INT_TRUE = 1;
public static final int INT_FALSE = 0;

public BoolInt() {
}

private int i = INT_FALSE;

public int getIntValue() {
return i;
}

public boolean getBoolValue() {
return i==INT_TRUE;
}

public void setIntValue(int i) throws Exception {
// if the user doesn't enter 1 or 0 throw exception
if (i!=INT_TRUE || i!=INT_FALSE) throw new Exception("your message");

this.i=i;
}

public void setBoolValue(boolean b) {
i = (b)?INT_TRUE:INT_FALSE
}
}``````
