Examples of Get in Java

Introduction

In Java, we can determine various things using these examples. These examples are very important for beginners.

Get Host Name in Java

This is used to determine the hostname in Java.

Example

package test;
import java.net.*;
import java.io.*;
public class Test {
public static void main(String[] args) {
try {
InetAddress adrs = InetAddress.getLocalHost();
byte[] ipAdrs = adrs.getAddress();
String hostname = adrs.getHostName();
System.out.println("Host Name is = " + hostname);
} catch (UnknownHostException e) {}
}
}

Output

Get Memory in Java

We can easily determine the memory size in Java using the following code.

Example

package test;
public class Test {
public static void main(String[] args) {
System.out.println("Total Memory" + Runtime.getRuntime().totalMemory());
System.out.println("Free Memory" + Runtime.getRuntime().freeMemory());
}
}

Output

Get Current Month in Java

This example will show you how to get the current month in Java.

Example

package test;
import java.util.Calendar;
public class Test {
public static void main(String[] args) {
String[] months_name = {"JAN", "FEB", "MAR", "APR", "MAY", "JUN",
"JUL", "AUG", "SEP", "OCT", "NOV", "DEC"
};
Calendar calndr = Calendar.getInstance();
String month = months_name[calndr.get(Calendar.MONTH)];
System.out.println("Month Name is : " + month);
}
}

Output

Get Class Name in Java

This example will print the class name in Java.

Example

public class Test {
public static void main(String args[]) {
new Test().hi();
}
void hi() {
try {
throw new Exception("Exception");
} catch (Exception e) {
System.out.println(e.getStackTrace()[1].getClassName());
}
}
}

Output

Get Character from String

In this example, we will remove characters from the string.

Example

package test;
public class Test {
public void StringToChar() {
String strng = "LAPTOP";
char[] chr_arr = strng.toCharArray();
for (char c: chr_arr)
System.out.println(c);
}
public static void main(String[] args) {
new Test().StringToChar();
}
}

Output

Get Current Time in Java

This example will give you the current time in Java.

Example

package test;
public class Test {
public static void main(String[] args) {
java.util.Date current_time = new java.util.Date();
System.out.println(new java.sql.Time(current_time.getTime()));
}
}

Output

Get Difference of Two Dates

This example will determine the difference between two given dates in a number of days.

Example

package test;
import java.util.*;
public class Test {
public static void main(String args[]) {
Test diff = new Test();
}
Test() {
Calendar calndr1 = new GregorianCalendar();
Calendar calndr2 = new GregorianCalendar();
calndr1.set(2005, 12, 12);
calndr2.set(2013, 12, 12);
System.out.println("Days= " + Between(calndr1.getTime(), calndr2.getTime()));
}
public int Between(Date D1, Date D2) {
return (int)((D2.getTime() - D1.getTime()) / (1000 * 60 * 60 * 24));
}
}

Output
