int a=5,b=10; System.out.println("var1="+a+" var2="+b); output: var1=5 var2=10

With printf you can format what you want to print a bit easier than with println. Example: String firstName = "John"; String lastName = "Doe"; int age = 41; System.out.println("Name: " + firstName + " " + lastName + "\n" + Age: " + age); System.out.printf("Name: %s %s\nAge: %d\n", firstName, lastName, age); As you can see, the second is a bit shorter and easier to read. But the true power of printf is the formatting. - %d is a format specifier for integer values. In the above example is used for the age variable. It tells to the printf method, that there should be an integer in the arguments. And it should be at the right place: In the example we have two strings (the names), and then the age variable: %s %s %d => the variables should be in the same order: firstName, lastName, age \n is escape character to go on the next line But more about what the format specifiers can do, look here: https://sharkysoft.com/archive/printf/docs/javadocs/lava/clib/stdio/doc-files/specification.htm

int a = 5; int b = 10; System.out.println(a + " " + b); // 5 10 // You can use the print format method - printf // %s - Strings, %d - Integers, %f - Float, \n - for new line System.out.printf("%d %d\n", a, b); // 5 10
