java - Why is the finally statement needed if there is no catch block? -

i know try statement useless without catch or finally, , finally clause optional in try-catch block. however, when write try statement without catch or finally, compiler suggests inserting finally clause complete try statement.

for example:

try {     (int j = 0; j <= i.length; j++) {             system.out.println(i[j]);     } } catch (arrayindexoutofboundsexception e) {         system.out.println("catch"); } //no errors  try {     (int j = 0; j <= i.length; j++) {         system.out.println(i[j]);     } } //syntax error 

error code:

exception in thread "main" java.lang.error: unresolved compilation problem:  syntax error, insert "finally" complete trystatement  @ driver.main(driver.java:12) 

why finally recommended statement implement? why not catch?

"i might want happen despite exception being thrown, may not looking handle specific exception in specific way, may want ensure @ least generic happens. if can't handle it, @ least something." looking confirm on this.

because try without catch or finally makes no sense @ all. nothing you'd have same result if omit try-block.
