Java - convert int to double
6 points
Short solution:
xxxxxxxxxx1
int intNumber = 200;2
double doubleNumber = (double) intNumber; // 200Another simple solutions:
xxxxxxxxxx1
// solution 2 (implicit casting)2
int intNumber2 = 200;3
double doubleNumber2 = intNumber2; // 2004
5
// solution 36
int intNumber3 = 200;7
double doubleNumber3 = 1.0d * intNumber3; // 200 // or: 1.0 * intNumber38
9
// solution 410
int intNumber4 = 200;11
Double doubleNumber4 = new Double(intNumber4); // 20012
13
// solution 514
int intNumber5 = 200;15
Double doubleNumber5 = Double.valueOf(intNumber5); // 20016
17
// solution 618
Integer number6 = 200;19
double doubleNumber6 = number6.doubleValue(); // 200In java we can convert int to double in following ways.
