How to compare two integer objects in Java?
This method compares two integer objects numerically. It returns the result of the value 0 if Integer is equal to the argument Integer, a value less than 0 if Integer is less than the argument Integer and a value greater than 0 if Integer is greater than the argument Integer. This method is specified by Comparable Interface.
How to compare numbers or integers in Bash?
INT1 =100 INT2 =100 if [ $INT1 -eq $INT2 ]; then echo “exit status: $?” echo “Both integers are equal” else echo “exit status: $?” echo “Both integers are not equal” fi The output from this script returns zero exit status as both the variables have same number. In this sample script we will use -ne operator to check and compare variables.
How to check if a variable is greater than a number?
To check if the numbers in an variable are greater than or less than each other we use -gt or -lt operator. In this example we know that INT1 is greater than INT2 but let us verify this using comparison operators
