In Java, you can print text or other values to the console using the following methods:
- System.out.println():
-
This method prints the text or value and moves the cursor to a new line after printing.
-
Example:
java System.out.println("Hello World!"); System.out.println("I am learning Java.");
-
Each call to
println()
results in output on a new line.
-
- System.out.print():
-
This method prints the text or value but does not move to a new line afterward. The cursor stays on the same line.
-
Example:
java System.out.print("Hello "); System.out.print("World!");
-
The output will be on the same line: "Hello World!"
-
- System.out.printf():
-
This method is used to print formatted text using format specifiers.
-
Example:
java double value = 5.984; System.out.printf("%.2f", value); // Prints value with 2 decimal places: 5.98
-
For printing variables along with text:
java
String name = "John";
System.out.println("Hello " + name);
For numeric calculations:
java
int x = 5;
int y = 6;
System.out.println(x + y); // Outputs 11
In summary:
- Use
println()
to print with a newline. - Use
print()
to print without a newline. - Use
printf()
for formatted output.
These methods are part of the System.out
object which is an instance of
PrintStream
class in Java used for console output.
