A clever way to replace Math functions You can shorten if-else statements through the a?b:c syntax, where a is the statement of if, b is the result of if, and c is the result of else. static vo...
Booleans are replaceable Java, like Python, has pretty convenient yet nasty ways to golfing down code through comparison operators. Especially this case, this time with booleans. You can compare i...
Java (JDK), 150 bytes interface M{static void main(String[]a){int i=new java.util.Scanner(System.in).nextInt(),j=0;for(;i!=1;j++){i=i%2==1?i*3+1:i/2;}System.out.print(j);}} Try it online! Fr...

Use interface The special thing about this is that it lets you drop public when you originally call a class to run the main function. class F{public static void main(String[]a{}} interface M{sta...
Use for(;;) instead of while(true) The title's self-explanatory. A byte saver.
This is a list of golfing tips for the language known as Java. If you have a tip, add it in!
Challenge Make a program that takes input of 3 non-negative integers: a result and 2 other values that once calculated results to the 3rd value. The program must figure out how to get the 2 fir...
