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
at PrintMessage.main(PrintMessage.java:24)
