Method

intlongToInt(Long l)
Converts a Long to an int with special attention to overflow issues. 
if (l != null) {
    if (new Long(Integer.MAX_VALUE).compareTo(l) == -1) {
        return Integer.MAX_VALUE;
    } else if (new Long(Integer.MIN_VALUE).compareTo(l) == 1) {
        return Integer.MIN_VALUE;
    return l.intValue();
return 0;
intlongToInt(Long l)
long To Int 
if (l != null) {
    if (new Long(Integer.MAX_VALUE).compareTo(l) == -1) {
        return Integer.MAX_VALUE;
    } else if (new Long(Integer.MIN_VALUE).compareTo(l) == 1) {
        return Integer.MIN_VALUE;
    return l.intValue();
return 0;
intlongToInt(long value)
Checked conversion from long to int 
if (value > Integer.MAX_VALUE || value < Integer.MIN_VALUE) {
    throw new IllegalArgumentException(value + " is out of Integer's bound");
return (int) value;
int[]longToInt(long[] values)
long To Int 
if (values == null) {
    return null;
int[] results = new int[values.length];
for (int i = 0; i < values.length; i++) {
    results[i] = (int) values[i];
return results;
...
int[]longToIntArr(long[] longArr)
long To Int Arr 
int[] intArr = new int[longArr.length];
for (int i = 0; i < longArr.length; i++) {
    intArr[i] = (int) longArr[i];
return intArr;
int[]longToIntArray(long value)
long To Int Array 
int[] digits = Long.toString(value).chars().map(c -> c -= '0').toArray();
return digits;
intlongToIntBounds(long value)
casts a long to an int, but if the long is outside the int-range, it will mapped to the end of the range 
if (value > Integer.MAX_VALUE)
    return Integer.MAX_VALUE;
else if (value < Integer.MIN_VALUE)
    return Integer.MIN_VALUE;
else
    return (int) value;
byte[]longToIntBytes(long a)
Convert a long value to a 4-byte array. 
byte[] returnByteArray = new byte[4]; 
returnByteArray[0] = (byte) ((a & 0xff000000) >> 24);
returnByteArray[1] = (byte) ((a & 0x00ff0000) >> 16);
returnByteArray[2] = (byte) ((a & 0x0000ff00) >> 8);
returnByteArray[3] = (byte) ((a & 0x000000ff));
return returnByteArray;
intlongToIntClip(final long value)
long To Int Clip 
final int intValue = (int) value;
if (value == intValue) {
    return intValue;
} else if (value >= Integer.MAX_VALUE) {
    return Integer.MAX_VALUE;
} else {
    return Integer.MIN_VALUE;
IntegerlongToInteger(final long value)
long To Integer 
return (int) value;
