Examples of Java String Format Specifiers
Example 1
Java
// Java program to demonstrate Concatenation of Arguments// to the string using format() method// Main classclass GFG { // Main driver method public static void main(String args[]) { // Custom input string to be formatted String str1 = "GFG"; String str2 = "w3wiki"; // %1$ represents first argument // %2$ second argument String str = String.format( "My Company name" + " is: %1$s, %1$s and %2$s", str1, str2); // Print and display the formatted string System.out.println(str); }} |
Output
My Company name is: GFG, GFG and w3wiki
Example 2
Java
// Java program to Illustrate Left Padding// using format() method// Main classclass GFG { // Main driver method public static void main(String args[]) { // Custom integer number int num = 7044; // Output is 3 zero's("000") + "7044", // in total 7 digits String str = String.format("%07d", num); // Print and display the formatted string System.out.println(str); }} |
Output
0007044
