1) Update the existing map without creating another map. 2) Write code to show the deadlock. 3) Find the maximum number from the given array. 4) Write the signature of service returning all the records from the provided table. 5) Explain about the Json format.
What if we insert with key null to a HashMap?
You are given a matrix having 0s & 1s where each row & column is sorted also. So need to find the maximum matrix of 1s. e.g. Below is the given matrix, note each row & column is sorted. {0,0,0,0,1} {0,0,0,1,1} {0,1,1,1,1} {0,1,1,1,1} {1,1,1,1,1} so max matrix having 1s can be- 1,1,1,1 1,1,1,1 1,1,1,1
Questions were general like on Spring, Core Java, microservices.
In coding test, one question was to find the count of unique characters in the given string. Other question was to get the country code of the given country from the given URI where you can pass country name name & get some data. Then you will need to parse that data to fetch the country code field data. The manager was looking for some 10+ years experienced person who designed & built the enterprise level applications from scratch, means some person who can confidently fake his/her intelligence & can fit to DBS policies to fool the people. He wanted to know that design. In short, its all fake show-off here that they do exceptional work but reality will be total opposite.
General discussion about microservices & DB
The questions of the 3 leads are acceptable. They are verifying my knowledge and experiences based on sample scenarios However, one software developer (indian guy) asked me this questions: What is the difference between final, finally and finalize? What are the different http status codes?
