void main() { int numOfApples = 16; String msg = String.format("There are %s apples", numOfApples); System.out.println(msg); } The example uses String.format to do int to String conversion. Using string concatenationWhen we use the + operator on int and String parameters, the Java ...
The valueOf(long) factory uses this array inside: public static BigDecimal valueOf(long val) { if (val >= 0 && val < ZERO_THROUGH_TEN.length) return ZERO_THROUGH_TEN[(int)val]; else if (val != INFLATED) return new BigDecimal(null, val, 0, 0); return new BigDecimal(INFLATED_BIG...
Java does the heavy lifting and converts it down to int, like this: public static void main(String[] args) { Integer myInteger = new Integer(5000); //call a method and pass the Integer coolMethod(myInteger); } public static void coolMethod(int n) { //Java converts to int at run...
int actual = decimal.intValue(); assertThat(actual) .isNotEqualTo(expected) .isEqualTo(expected - Long.MAX_VALUE - 1); } At the same time, it’s a reasonable behavior, considering thebinarynumber representation.We cannot store more bits of information than anintcan take.In some scenarios...

In my opinion, using double is a viable option as long as it is accompanied by appropriate rounding measures. The precision of int x is 32-bit while that of float is 24-bit, hence even when divided by 1 there could be a rounding error. However, double has a precision of 53-bit whic...
