Java String format() with examples

// Java program to demonstrate
// working of format() method

class Gfg1 {
public static void main(String args[])
{
String str = "GeeksforGeeks.";

// Concatenation of two strings
String gfg1 = String.format("My Company name is %s", str);

// Output is given upto 8 decimal places
String str2 = String.format("My answer is %.8f", 47.65734);

// between "My answer is" and "47.65734000" there are 15 spaces
String str3 = String.format("My answer is %15.8f", 47.65734);

System.out.println(gfg1);
System.out.println(str2);
System.out.println(str3);
}
}

class Gfg2 {     public static void main(String args[])     {         String str1 = "GFG";         String str2 = "GeeksforGeeks";            //%1$ represents first argument, %2$ second argument         String gfg2 = String.format("My Company name" +                   " is: %1$s, %1$s and %2$s", str1, str2);            System.out.println(gfg2);     } }

Output:

My Company name is: GFG, GFG and GeeksforGeeks

// Java program to show 

// left padding using 

// format() method 

  

class Gfg3 { 

    public static void main(String args[]) 

    { 

        int num = 7044; 

  

        // Output is 3 zero's("000") + "7044", 

        // in total 7 digits 

        String gfg3 = String.format("%07d", num); 

  

        System.out.println(gfg3); 

    } 

} 







Output:
