Java/Perl - "sprintf function in java" or "string format"

In Java, the String.format() method can be used to format a string with placeholders for variable values, similar to the sprintf() function in Perl.

Here is an example of how to use String.format() in Java:

int number = 42;
String message = String.format("The number is %d.", number);

System.out.println(message);  // Outputs "The number is 42."

The %d placeholder in the format string is replaced with the value of the number variable. You can use different placeholders for different types of values, such as %f for floating-point numbers, %s for strings, and %x for hexadecimal numbers.

You can also use formatting options to specify the width, precision, and alignment of the formatted value. For example, %5d specifies a minimum width of 5 characters, left-aligned, and padded with spaces if necessary.

For more information about using String.format() and the available formatting options, you can consult the Java documentation or search online for examples and tutorials.
