# Calculate Powers of Integers in Java

If you’ll want to calculate the powers of Integers in Java, then you are able to do one of many following:

## Possibility 1 – Utilizing `for` loops#

``````public class Energy {
public static void major(String args[]){
int quantity = 5;
int energy = 3;
int consequence = calculatePower(quantity,energy);
System.out.println(quantity+"^"+energy+"="+consequence);
}
static int calculatePower(int num, int energy){
if (num > 0 && energy==0){
} else if(num == 0 && energy>=1){
return 0;
} else{
for(int i = 1; i<= energy; i++)
}
}
}
``````

## Possibility 2 – Utilizing Recursion#

``````public class Energy {
public static void major(String args[]){
int quantity = 3;
int energy = 3;
int consequence = CalculatePower(quantity,energy);
System.out.println(quantity+"^"+energy+"="+consequence);
}
static int CalculatePower (int num, int pow){
if (pow == 0)
return 1;
else
return num * CalculatePower(num, pow - 1);
}
}
``````

## Possibility 3 – Utilizing `Math.pow()`#

``````import java.lang.Math;
public class Energy {
public static void major(String args[]){
int quantity = 6;
int energy = 3;
double consequence = CalculatePower(quantity,energy);
System.out.println(quantity+"^"+energy+"="+consequence);
}
static double CalculatePower (int num, int pow){
return Math.pow(num,pow);
}
}
``````
