size of integer in java code example
Example 1: java how to find length of int
int x = 1234;
int lengthOfInt = String.valueOf(x).length();
Example 2: how to get length of integer in java
int length = (int) (Math.log10(number) + 1);
Example 3: java get bigger int
int biggerNum = max(int a, int b);
Example 4: all data types in java
Data Type Size Stores
byte 1 byte whole numbers from -128 to 127
short 2 bytes whole numbers from -32,768 to 32,767
int 4 bytes whole numbers from -2,147,483,648 to 2,147,483,647
long 8 bytes whole numbers from -9,223,372,036,854,775,808 to 9,223,372,036,854,775,807
float 4 bytes fractional numbers; sufficient for storing 6 to 7 decimal digits
double 8 bytes fractional numbers; sufficient for storing 15 decimal digits
boolean 1 bit true or false values
char 2 bytes single character/letter or ASCII values
Example 5: how to get length of integer in java
int length = 0;
long temp = 1;
while (temp <= number) {
length++;
temp *= 10;
}
return length;
