Method

inttoInt(long l)
Converts long value to int under the conditions that the long value is representable as an int. 
if (l < Integer.MIN_VALUE || l > Integer.MAX_VALUE) {
    throw new IllegalArgumentException(l + " cannot be cast to int without changing its value.");
return (int) l;
inttoInt(long l)
to Int 
if (l < Integer.MIN_VALUE || l > Integer.MAX_VALUE)
    throw new ArithmeticException("Value (" + l + ") cannot fit into int");
return (int) l;
inttoInt(long unsignedInt)
Converts a long containing an unsigned int value to the corresponding signed int value and returns the result as an int 
if (unsignedInt < 0 || unsignedInt > MAX_INT) {
    throw new IllegalArgumentException(String.format(
            "Unsigned byte values should be in the range 0..%1$d, got: %2$d", MAX_INT, unsignedInt));
return (int) unsignedInt;
int[]toInt(long[] a)
to Int 
int[] b = new int[a.length];
for (int i = 0; i < a.length; i++) {
    b[i] = (int) a[i];
return b;
inttoInt(Number num)
to Int 
if (num == null) {
    return 0;
} else {
    return num.intValue();
inttoInt(Number value)
to Int 
long valueLong = value.longValue();
if (valueLong < Integer.MIN_VALUE || valueLong > Integer.MAX_VALUE) {
    throw new IllegalArgumentException(valueLong + " Casting the long to an int will change its value");
return (int) valueLong;
inttoInt(Number wrapped)
to Int 
if (wrapped == null) {
    return -1;
return wrapped.intValue();
inttoInt(Object bean, int defaultValue)
to Int 
try {
    return (null != bean) ? Integer.parseInt(bean.toString()) : defaultValue;
} catch (Exception e) {
    e.printStackTrace();
return defaultValue;
inttoInt(Object num)
to Int 
int x;
if (num instanceof Long) {
    x = ((Long) num).intValue();
} else if (num instanceof Double) {
    x = ((Double) num).intValue();
} else if (num instanceof String) {
    x = Integer.getInteger((String) num);
} else {

inttoInt(Object num, int defValue)
to Int 
if (num != null) {
    String value = String.valueOf(num);
    try {
        return Integer.parseInt(value);
    } catch (Exception e) {
