Java example program to print message without using System.out.println()

Is it possible to print message without using system.out.println?




Yes its possible to print message without using System.out.println("");

System.out.write("www.corejavawithselenium.blogspot.in\n".getBytes());
 System.out.format("%s", "www.java.com \n")
 PrintStream myout =  new PrintStream(new FileOutputStream(FileDescriptor.out));
   myout.print("www.corejavawithselenium.blogspot.in \n");
System.err.print("This is custom error message");
System.console().writer().println("Hai");

1.System.out.write(Byte [] arg0);

System.out.write(Byte [] arg0) method The java.io.FilterOutputStream.write(byte[] b) method writes b.length bytes to this output stream.

package com.instanceofjava;

public class PrintMessage {

public static void main(String[] args) throws IOException{

       System.out.write("Hello World".getBytes());
}
}

Output:

Hello World

2. PrintStream  java.io.PrintStream.format(String arg0, Object... arg1)

System.out.format("format",Object obj) by using this method we can format the text and print

package com.instanceofjava;

public class PrintMessage {

public static void main(String[] args){

        System.out.format("%s", "James");
}

}

Output:

James

3. FileDescriptor:

Create PrintStream object by passing FileOutputStream(FileDescriptor.out) object as an argument to the constructor
package com.instanceofjava;

public class PrintMessage {

public static void main(String[] args){

       PrintStream myout =  new PrintStream(new FileOutputStream(FileDescriptor.out));
          myout.print("i love Java");
}
}

Output:

i love java


4. System.err.print(""):

We can use System.err.print("") method to print the message actually its used to print error message
package com.instanceofjava;

public static void main(String[] args){

       System.err.print("This is custom error message");
}
}

Output:

This is custom error message


5.System.console().writer().println("");

System.console() returns null if your application is not run in a terminal System.console() provides methods for reading password without echoing characters

package com.instanceofjava;

public static void main(String[] args){

       System.err.print("This is custom error message");
}
}

Output:

This is custom error message Exception in thread "main" java.lang.NullPointerException
