try-catch-finally中哪个部分可以省略？

package constxiong.interview;
 
public class TestOmitTryCatchFinally {
 
    public static void main(String[] args) {
        omitFinally();
        omitCatch();
    }
    
    /**
     * 省略finally 语句块
     */
    public static void omitFinally() {
        try {
            int i = 0;
            i += 1;
            System.out.println(i);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    
    /**
     * 省略 catch 语句块
     */
    public static void omitCatch() {
        int i = 0;
        try {
            i += 1;
        } finally {
            i = 10;
        }
        System.out.println(i);
    }
}
