Gradle Installation Steps


Download and unpack Gradle distributions from the Gradle web site: Gradle Downloads.

Gradle requires a Java JDK or JRE to be installed, java version 6 or higher is must. Check java version in your system by using below command:

java -version

Gradle ships with its own Groovy library, therefore Groovy does not need to be installed. Any existing Groovy installation is ignored by Gradle.

Gradle uses whatever JDK it finds in your path. Alternatively, you can set the JAVA_HOME environment variable to point to the installation directory of the desired JDK.

You must add GRADLE_HOME/bin to your PATH environment variable. "GRADLE_HOME" is the folder path where you have unpacked the gradle distribution. Here is the example to set path.

/******  In MAC OS  ******/
export PATH=$PATH:/Users/java2novice/softwares/gradle-2.1/bin

/******  In Windows OS  ******/
SET PATH=%PATH%;C:\java2novice\gradle-2.1\bin

To check if gradle is properly installed or not run "gradle -v" command, and you should get similar response as shown below:

String Vs StringBuffer
We know that String is immutable object. We can not change the value of a String object once it is initiated. If we try to change the value of the existing String object then it creates new object rather than changing the value of the existing object. So incase, we are going to do more modificatios on String, then use StringBuffer. StringBuffer updates the existing objects value, rather creating new object.
